Natural rubber nanocomposites system

The barrier properties of starch nanocrystals/natural rubber nanocomposites were also investigated [39]. For these systems, the water vapour transmission rate, the diffusion coefficient of oxygen, the permeability coefficient of oxygen and its solubility, were measured. It was observed that the permeabiUty to water vapour, as well as to oxygen, decreased when starch nanocrystals wctc added These effects were ascribed to the platelet-like morphology of the nanocrystals. [Pg.416]

This technique has found the following applications in addition to those discussed in Sections 10.1 (resin cure studies on phenol urethane compositions) [65], 12.2 (photopolymer studies [66-68]), and 13.3 (phase transitions in PE) [66], Chapter 15 (viscoelastic and rheological properties), and Section 16.4 (heat deflection temperatures) epoxy resin-amine system [67], cured acrylate-terminated unsaturated copolymers [68], PE and PP foam [69], ethylene-propylene-diene terpolymers [70], natural rubbers [71, 72], polyester-based clear coat resins [73], polyvinyl esters and unsaturated polyester resins [74], polyimide-clay nanocomposites [75], polyether sulfone-styrene-acrylonitrile, PS-polymethyl methacrylate (PMMA) blends and PS-polytetrafluoroethylene PMMA copolymers [76], cyanate ester resin-carbon fibre composites [77], polycyanate epoxy resins [78], and styrenic copolymers [79]. [Pg.579]

This book on natural rubber presents a summary of the present state-of-the-art in the study of these versatile materials. The two volumes cover all the areas related to natural rubber, from its production to composite preparation, the various characterization techniques and life cycle assessment. Chapters in this book deal with both the science of natural rubber - its chemistry, production, engineering properties, and the wide-ranging applications of natural rubber in the modern world, from the manufacture of car tyres to the construction of earthquake protection systems for large buildings. Although there are a number of research publications in this field, to date, no systematic scientific reference book has been published specifically in the area of natural rubber as the main component in systems. We have developed the two volumes by focusing on the important areas of natural rubber materials, the blends, IPNs of natural rubber and natural rubber based composites and nanocomposites their preparation and characterization techniques. The books have also profoundly reviewed various classes of fillers like macro, micro and nano (ID, 2D and 3D) used in natural rubber industries. The applications and the life cycle analysis of these rubber based materials are also highlighted. [Pg.6]

Kong et al. [115] synthesized hy melt-intercalation silicone rubber (SR)/clay nanocomposites using synthetic Fe-montmoriUonite (Fe-MMT) and natural Na-MMT which were modified by cetyltrimethylammoniumbromide, surfactant. They obtained exfoliated and intercalated nanocomposites. With TGA and mechanical performance found that with the presence of iron significantiy increased the onset temperarnre of thermal degradation in SR/Fe-MMT nanocomposites. In addition, the thermal stability, gel fraction and mechanical property of SR/Fe-MMT were different from the SR/Na-MMT nanocomposites, so the iron not only in thermal degradation but also in the vulcanization process acted as an antioxidant and radicals trap. A new flame-retardant system, SR/Fe-OMT based on an EVA matrix, was examined Fang et al. [ 116]. The experimental analyses showed that the exfoliated Fe-OMT had better dispersion in the EVA matrix than Na-OMT, and it was more effective in improving... [Pg.177]
