Abstract:

Epoxy resins are widely used in different industries as adhesives, surface coatings and matrix of composites. This is due to their unique properties including excellent mechanical and electrical properties, thermal and chemical stability. The pure or virgin epoxy resins have high viscosity and the inherent toughness of polymer network is low. Some additives like diluents, fillers (micro or nano) extenders, adhesion promoters and toughening agents usually are being used in epoxy formulations in order to make a suitable or advanced epoxy matrix. Much research has been carried out to enhance the toughness of the cured epoxy resins. The general strategies used are introduction of flexible chain into the network structure (e.g. ether linkage), compatible blending with flexible or ductile polymer, reduction in crosslink density of network and introduction of a suitable matter like rubber, thermoplastic or rigid particles as a second phase. For a decade we have done a comprehensive work in the area of modifications of epoxy resins in order to develop an advanced epoxy matrix system suitable for making glass or carbon/epoxy prepregs. These includes selection of suitable epoxy resins, curing systems, modification of an epoxy system by using reactive diluents, toughening of a system by using carboxyl-terminated Copolymer of Butadiene and Acrylonitrile (CTBN), poly (propylene oxide) based amine (Jeffamine D-400) or long-chain hardener and Hydroxyl Terminated Poly butadiene (HTPB), micro capsulation of curing agent and developing new latent accelerator

Abstract:

Irradiation of poly (4-ethoxystyrene) in solid films and at 265 nm at room temperature showed a gradual photo-degradation of polymeric chains. Degradation was accelerated by the presence of air and rise in temperature. The degradation process was followed by UV-VIS, fluorescence and FT-IR Spectroscopic techniques. The intensity of absorption spectra was increased by the increase in irradiation time in both solid films and in solution; on the other hand the intensity of fluorescence was decrease upon the increase in irradiation time and increase in the amount of blended phthalate and terephthalate plasticizers. Some kinetics work was applied to the results on fluorescence intensity of the excimeric emission to evaluate the quenching efficiencies and photo quenching rate constant by applying Al Ani Hawi equation. The analysis of the FT-IR spectra of the irradiated and non-irradiated samples, showed a noticeable formation of new bands and their intensity was found to increase with the increase in irradiation time and also with the increase in the amount of added plasticizer. In addition, the observed increase in the intensities of the carbonyl and hydroxyl absorption regions of the FT-IR spectra, providing evidence for the photo-degradation as well as photo-oxidation of polymeric chains

Abstract:

In modern years there has been an enormous interest in electrochromic technology, which triggered the designing and fabrication of efficient electrochromic devices (ECD) which work on the phenomena of electrochromism, in which a reversible optical modulation in the materials can be achieved by intercalation/deintercalation of small cations and electrons by the application small electric field. Tungsten trioxide (WO₃) is one among the various EC transition metal oxides recognized as best EC material in thin film form. It exhibits large optical modulation, good durability, stability, low power consumption for the prepared ECDs.

                                 WO₃(Transparent) + xH⁺ + xe^-  ↔ H_xWO₃(Blue)

        In the present work, WO₃ thin films were prepared by electron beam evaporation technique at various oxygen partial pressures (PO₂) ranging from 2x10^-3 to 2x10^-5 mbar and at the substrate temperature of 250 ^oC. The films were deposited onto well cleaned glass, ITO coated glass and silicon substrates. The influence of oxygen partial pressure on the growth, morphology, optical and electrochromic properties have been investigated. The XRD studies revealed that the phase transformation taken place from orthorhombic to monoclinic with respect to PO₂ from 2x10^-3 to 2x10^-5 mbar. The maximum optical bandgap of   3.28 eV was obtained for the films deposited at 2x10^-5 mbar and decreased to 2.66 eV for the films deposited at 2x10^-3 mbar. The coloration efficiency of WO₃ films at the wavelength of 550 nm were found to be 50.84, 29.56 and 24.95 cm²/C for the films deposited in the PO₂ of 2x10^-3, 2x10^-4 and 2x10^-5 mbar respectively.

Abstract:

Future plan to make PET Heavy metal free for human friendly packaging material, toxic heavy metal has to be replaced with light metal catalyst is the ultimate objective. Adverse effects of heavy metals including, life threatening diseases by damaging of brain, kidney, lungs in fact damage to all major organs. At present heavy metal migration limits are 40 ppb. For one of its kind project, series of trial were designed, out of which first two light metal catalyst trials on one of the world largest PET production lines did not results in the desired heavy metal free process with high process stability and high production quality as demonstrated on pilot lines. Therefore, a second pilot plant trial was executed to define root causes. In the latest pilot plant trial results from previous pilot plant trials could be repeated and exceeded by switching the new catalyst injection point from post-ester (second chamber of reactor) into esterification (first chamber of reactor), respective in the paste tank (giving it better mixing and more residence time). It has to be mentioned that in early commercial line trials it was thought that the new catalyst (light metal) could be partly deactivated in the easterification reactor due to too high end groups (COOH) and water content and that it would be most safe to feed the catalyst into the post ester reactor. Furthermore the esterfication reaction is auto-catalyzed by H+ from the COOH and can run without any catalyst. After the commercial trials, the suspicion arose that the catalyst suffers a poor mixing when fed in the post-ester and that it should be tested to feed the catalyst into the paste or esterification chamber to ensure complete mixing. During pilot plant trial, it was a great surprise when feeding the new catalyst (light metal) in the esterification reactor that even with only 7.5 ppm it was possible to reach a stable viscosity after the melt phase polymerization of 0.80 dl/g at 100% name plate capacity. The slight deterioration in optical quality was later easy to adjust to standard color with addition of a small amount of toner. Another finding in that trial was that the esterfication conversion should be above 90% otherwise a loss of viscosity after melt phase polymerization is possible. Along with minimizing human health concerns, stable process, energy efficient and better optical quality in PET are of prime interest in the establishment of light metal catalyst.

Abstract:

Nanotechnology can be defined as research for the designing synthesis and manipulation of the structure of particles with dimension smaller than 100 nm. Metal nanoparticles have been studied extensively because of their unique physicochemical properties. Biological methods of nanoparticle synthesis using microorganisms, enzymes/proteins and plants extracts has been suggested as possible eco-friendly methods of synthesis alternatives to physical and chemical methods. Recently, nanomedicine has become a leading research field. Scientists are involved in developing safe, effective, cheaper and less toxic drugs or carriers to combat diseases like cancer, epilepsy, etc. Use of plant for synthesis of nanoparticles could be advantageous over other environmentally benign biological process as this eliminates the elaborate process of maintaining cell cultures. Plant use can also be suitable scaled up for large scale synthesis of nanoparticles. In the plant mediated green chemistry approach, the reduction are of metals salts is very fast and the procedure itself requires no specific conditions unlike the physical and chemical. Therefore medicinal plants of well established therapeutic importance are being widely used for the Green synthesis. Medicinal plants are used by 80% of the world population for their basic health needs. India is the birth place of renewed system of indigenous medicines such as Siddha, Ayurveda and Unani.

Abstract:

In the current work, Chitosan (CS) underwent modification with Alginic acid (AG), Hydroxyapatite (HA), multi-walled Carbon Nanotubes (CNT) and cross-linked with Glutaraldehyde (GA). All products were characterized and compared with blank CS. All materials showed the characteristic bands of FT-IR spectroscopy. Thermal degradation of modified CS was also investigated by thermal analysis. There was a slight weight loss % up to 240 °C followed by Extensive Weight Loss (EWL) % up to 420 °C. After that, there was a slight weight loss until the end of measurement at 700 °C. EWL % depends on the modifier content. Generally, modified CS is more thermally stable than the unmodified ones. For CS/AG blends, thermal stability was higher for 10% AG content than others for both cross-linked and uncross-linked samples. In case of CS/HA composites, 20% HA modified CS showed higher thermal stability than others with no significant difference among them but significant if compared with the unmodified CS. For CS/HA/CNT composites, CNT helps samples to be thermally more stable than CS/HA composites. It would be more beneficial to use CNT only in the composite formation but the functions supplied to the composite by HA are sometimes crucial where the chemical structure and features of HA are required to be involved in the composite characteristics. Ability of matrices to uptake metal ions was determined by using Cu (NO₃) and it could be arranged as CS/AG/GA>CS/GA>CS/HA/CNT/GA>CS/HA/GA. Modified CS was used for drug delivery by using 5-Fluorouracil (FU) as antitumor model drug. Most of FU was released within 24 hours while maximum release was after 48 hours. It could be concluded that the ease of release of FU from the investigated matrices could be arranged from the fastest to the slowest matrix in the order of P111F>P121F>P311F>P411F>P321F>P421F

Helanka J Perera has completed her PhD from Oklahoma State University, USA and is currently an Chemistry Assistant Professor in Maths and Natural Science Department at Abu Dhabi Women’s College, UAE. Her research interests are in material science, surface modification on micro and nanomaterials, superhydrophobicity, hydrophobicity, polymer and surface characterization.

Abstract:

Superhydrophobic/hydrophobic coatings were made using Fluorinated (FS) and Non-Fluorinated (NFS) Silane treated Diatomaceous Earth (DE) with different polymeric resins/binders. These coatings have been characterized with contact angle measurements, scanning electron microscopy and thermogravimetric analysis. Contact angles greater than 150° were attainable if the particles were sufficiently coated with fluorinated and non-fluorinated coupling agents and also if there were enough particles in the coatings. The critical particle loadings depended on the resin/binder system used. The behavior of these surfaces mimics that from, for example, the lotus leaf as they had low surface energies and also appropriate nano-micro structures.
