Plasma induced degradation and surface electronic structure modification of Poly(3-hexylthiophene) films 10.1016/j.polymdegradstab.2017.12.010 2017-12-14 Plasma treatment is an environmentally friendly solution for modifying or nanostructuring the surface of several materials including photoactive polymers. The detailed characterization of the effect of plasma treatment on chemical and optoelectronic propertie...
Biodegradation rate of biodegradable plastics at molecular level 10.1016/j.polymdegradstab.2017.12.011 2017-12-13 Plastics are solid materials where biodegradation happens on the surface. Only the surface is affected by biodegradation while the inner part should not be readily available for biodegradation. Thus, at a laboratory level, the biodegradation rate is expected ...
Application of ammonia pretreatment to enable enzymatic hydrolysis of hardwood biomass 10.1016/j.polymdegradstab.2017.12.008 2017-12-12 Ammonia pretreatment greatly improves enzymatic hydrolysis of grass biomass, but is reported to be ineffective for hardwood biomass. Here, we examined the effectiveness of ammonia pretreatment of biomass from six hardwood species with different contents of xy...
Methanolysis of microbial polyester poly(3-hydroxybutyrate) catalyzed by Brønsted-Lewis acidic ionic liquids as a new method towards sustainable development 10.1016/j.polymdegradstab.2017.12.009 2017-12-11 Chemical recycling of bio-based polymer poly(3-hydroxybutyrate) (PHB) by methanolysis was discussed in detail from the perspective of biological refining. The results of methanolysis transformed PHB into ester monomer successfully by using some ionic liquids....
Effect of styrene butadiene rubber on the light pyrolysis of the natural rubber 10.1016/j.polymdegradstab.2017.12.006 2017-12-06 The use of styrene butadiene rubber (SBR) in tire rubber presents a challenge for the recycling of tire rubber because of its complex degradation behavior compared with that of natural rubber (NR). The effect of the composition of SBR on the degradation of NR...
The effect of de- and re-polymerization during heat-treatment on the mechanical behavior of Scots pine sapwood under quasi-static load 10.1016/j.polymdegradstab.2017.12.007 2017-12-06 Loss in strength and ductility is a major drawback for the heat-treatment of solid wood. Previous studies focused mainly on the de-polymerization of cell wall constituents as a cause and the importance of the preferential removal of hemicelluloses. This study...
Fire retardant sol-gel coated polyurethane foam: Mechanism of action 10.1016/j.polymdegradstab.2017.12.005 2017-12-05 This paper investigates the flame retardant (FR) mechanism of action of a flexible PU foam, flame retarded with a sol-gel coating made of a mixture of tetraethoxysilane (TEOS), methyl triethoxysilane (MTES), 3-amino propyl triethoxysilane (APTES) and diethyl ...
Thermal and mechanical properties of graphene oxide nanocomposite hydrogel based on poly (acrylic acid) grafted onto amylose 10.1016/j.polymdegradstab.2017.11.022 2017-12-05 In the present study, a nanocomposite hydrogel was synthesized based on poly (acrylic acid) grafted onto amylose (PAA-g-amylose) which was containing different loadings of graphene oxide (GO) nanosheets. The structural properties of optimized sample were char...
Multi detection in Size-Exclusion Chromatography of electron beam irradiated Ethylene Norbornene Copolymers 10.1016/j.polymdegradstab.2017.11.019 2017-12-05 Ethylene Norbornene Copolymers (ENCs) belong to the Cyclic Olefin Copolymers (COC) family and are used in numerous industrial fields. The goal of this paper is to compare the behavior under electron beam radiation of three grades of ENCs. Several radiation do...
Intercalation of phosphotungstic acid into layered double hydroxides by reconstruction method and its application in intumescent flame retardant poly (lactic acid) composites 10.1016/j.polymdegradstab.2017.12.004 2017-12-05 Phosphotungstic acid is a typical kind of superior catalysts, and it is hardly to intercalate into the layered double hydroxides (LDH) by ion-exchange process because of its low negative charge. In this work, a phosphotungstic acid intercalated MgAl-LDH (PWA-...
