Abstract In this work, neutron induced structural modifications, on the biaxially-oriented polyethylene naphthalate (BOPEN) film, were studied by X-ray diffraction technique (XRD), Fourier transform infrared spectroscopy (FTIR/ATR), scanning electron microscopy (SEM) and polarized light optical microscopy (PLOM). The irradiation with neutron was carried out, under air, at room temperature. The changes of the structure, in volume and in surface were evaluated under the impact of neutron’s flux composed by thermally neutrons and fast neutrons. The X-ray technique showed the effect of the neutron flux’s fluence on the crystallinity of the BOPEN, which was also determined through the FTIR/ATR spectroscopy, traduced by… More >

Abstract Accumulation of Microplastics (MPs) in diverse ecosystems is a growing global problem of our time. These are entering into the environment directly (micro-sized plastics manufactured purposefully) and by degradation of plastic products. Due to a diverse range of polymers and additives used to manufacture plastic products, the MPs of different chemical compositions are abundant in the environment. A detailed literature survey revealed that MPs -environment interaction is largely governed by these chemicals and other intrinsic properties of MPs viz. shape, size, density, surface charge, etc. The current investigation primarily aims to review different chemical and physical factors of MPs that… More >

Abstract Compression-molded epoxy methacrylate of bisphenol-C-jute/treated jute-banana/groundnut/ cane sugar/pineapple leaf/rice husk/wheat husk sandwich composites were fabricated under 5 MPa pressure at room temperature for 3 h. Alkali treated jute-natural fiber sandwich composites displayed considerably improved mechanical properties over untreated jute-natural fiber sandwich composites due to surface modification of the jute fibers. Both types of sandwich composites showed high water uptake tendency, excellent hydrolytic stability against acids, alkali, and salt solutions, and also a longer equilibrium time at 30o C. Alkali treated sandwich composites revealed a considerably lower water uptake tendency than untreated sandwich composites. Observed water uptake trend is H₂ SO₄… More >

Abstract The present work is focused on the study of antimicrobial and water absorption properties of the surface of grafted rayon fiber with quaternary ammonium-based salts containing 3- Acrylamidopropyl trimethyl ammonium chloride (APTAC) monomer induced by gamma radiation. Grafting was qualitatively confirmed by FTIR-ATR,TGA, SEM and by calculating grafting yield and grafting efficiency. The performance was examined for water absorbency and antibacterial efficacy (R) against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus). Study showed that water absorption, grafting yield and grafting efficiency increased steadily with the increase in monomer concentration and absorbed gamma irradiation dose up to a certain… More >

Abstract In this study, a multi-layered green polymer-based packaging composite assembled by active flavonoid Kaempferol grafted with starch-chitosan was prepared, and its characteristics and effect on meat storage, including physicochemical characteristics and antioxidant capacity, were analysed and evaluated at refrigeration conditions given four treatments: CON (control— without coating), SEC (with starch+chitin), P01 (with starch+chitin + 1% of Kaempferol) and P02 (with starch+chitin + 2% of Kaempferol). The addition of Kaempferol increased the antioxidant activity of meat and inhibited the lipid oxidation until day 24 upon migration effect; also improving meat acceptability. The Rancimat induction time confirmed the stability of both P01… More >

Abstract In this work, we have successfully cross-linked the different weight ratio of Chitosan-PVA blend with sulfuric acid. The effect of cross-linker on the properties of blends are studied by using different experimental technique. The cross-linked membrane provides higher ion exchange capacity due to the procurement of extra ionic hooping sites in the membrane. The compatibility of the blends are confirmed from the FTIR and DSC analysis. The crosslinking reaction fastening the phase transition behavior of the blends which reduces the glass transition temperature. The highly compatiblized cross-linked blend provides higher tensile strength and lower modulus at moderate temperature. The significant… More >

Abstract Polyether telechelics based on ethylene glycol,1,2-propylene glycol and 1,4- butylene glycol of with various molar masses and bearing at both terminals functional groups such as maleimide, itaconimide, nadimide and hydroxyl groups were individually examined as toughening agents for an unsaturated polyester resin (UPER). For a given telechelic, the toughening effect was evaluated at different mass ratios. The difference in toughening efficacy arose from the differential reactivity of the telechelics end groups combined with the unsaturation of the UPER with the reactive diluent, styrene. This causes a differential distribution of the polyether groups in the UPER matrices, resulting in a differential… More >

Abstract Biocompatible graphene derivative materials (GBMs) to harness the maximum potential of pristine graphene biologically, is the most important strategy for its advanced applications in pharmaceutical and other biomedical fields. Currently, scientists are trying to find this by using biopolymer nanocomposites or anchored materials. Nevertheless, tuning the bare GBMs towards biocompatibility is a beautiful approach to exploit the fundamental potential of pristine graphene vis-à-vis suppressing the effects of incorporated biopolymers or anchored materials. Herein, a large-scale, cost-effective, facile, and environment-friendly green synthetic strategy is used for the synthesis of reduced graphene oxide (rGO) nanosheet using L-ascorbic acid (L-AA) as a reducing/stabilizing/capping… More >

Abstract In this study, polysulfone based capillary ultrafiltration membranes with desired characteristics were indigenously developed and their performance was evaluated with respect to turbidity removal from raw sea water. Capillary membranes were spun with in-house fabricated spinneret using polymer casting solution (dope solution) of different compositions having different viscosity using polyvinyl pyrrolidone (PVP) as pore-forming agent. Different experimental conditions namely dope pressure, bore fluid flow rate and air gap distance are optimized to get membranes of desired properties. Test results of individual capillaries in terms of pure water permeability (PWP), separation of single uncharged solutes like polyethylene glycol (PEG) and mechanical… More >

Abstract In this work, a pure gum mould made of prevulcanized natural rubber/cloisite-Na⁺ nanocomposite (PVNR/CN) was prepared and characterized for ornament application. The suitable conditions to prepare PVNR/CN latex mixtures and the properties of the resulting PVNR/CN nanocomposites were investigated. The optimum CN concentration in the latex mixture was 1.0 phr, with the properties of 60 wt% total solid content, more than 600 sec mechanical stability time, lower than 350 cP Brookfield viscosity, and pH 10. The properties of PVNR/CN nanocomposite showed high strength, moderate hardness, and good thermal stability. The morphology by TEM showed well dispersion of CN particles in… More >

Abstract Silk fibroin (SF) with renewability, biocompatibility and biodegradability shows potential application in various fields including biomedicine, tissue engineering, and wearable electronic devices. Herein, SF is used to exert effective reinforcement of polyvinyl alcohol (PVA) composite film to further improve its practicability. As such, PVA/SF composite films were prepared for the first time using a facile approach. The films were characterized to investigate possible interaction of PVA with SF. Meanwhile, systematic investigations have also been completed to explore the influences of PVA/SF mass ratio on the mechanical properties (tensile strength, elongation at break), biodegradability and biocompatibility, the morphology, crystallinity, chemical structure… More >
