Eva Copolymer

Nanocomposites of ethylene vinyl acetate (EVA) copolymer, polystyrene (PS) nanoparticles, and montmorillonite (MMT) were prepared by latex compounding. The nanolatex of PS was synthesized by differential microemulsion polymerization and then blended with EVA at EVA/PS dry weight ratios of 90/10, 80/20, and 70/30, before mixing with MMT at 1, 3, or 5 parts per hundred rubbers. The latex composite mixtures were cast on a glass mold and compressed into thin sheets. The nanocomposites were characterized for their structures, mechanical properties, and thermal behaviors. The tensile strength, Young’s modulus, storage modulus, and thermal stability were all improved with the incorporation of MMT, although the extent of such depended upon and varied with the EVA/PS ratio of the nanocomposite.

Promising Area

Joining thin sheets of aluminium and its alloys is a promising area in the field of joining materials. Nowadays, joining methods that do not melt the material itself are increasingly being utilised. This paper deals with adhesive bonding of aluminium alloy A5754 by two-component epoxy resins. Theresults show that joints bonded by Hysol 9466 have appropriate mechanical properties, but that joints bonded by Hysol 9492 have better thermal stability.

Rubber Nanocomposites

Natural rubber (NR) is representative biomass polymer and the effective uses are strongly contributed to sustainable society. This chapter presents the innovative and advanced rubber nanocomposites with polystyrene-encapsulated silica nanohybrids (PS-nSiO2) subsequently used as a nanofiller for NR and NR/styrene butadiene rubber (NR/SBR). The PS-nSiO2 were prepared via ‘in situ' differential microemulsion polymerization. The core-shell nanohybrids of PS-nSiO2 were achieved with an average diameter of 40 nm using a smaller amount of surfactant, compared to microemulsion polymerization method. Moreover, the effects of the NR and NR/SBR filled with PS-nSiO2 nanohybrids on the mechanical properties, thermal stability, flammability and morphology are also discussed. The results indicated that the encapsulation of nSiO2 with PS can provide not only the well-dispersion of nanoparticles in the rubber matrix but also the synergistic properties of two components from the polymer and the inorganic nanoparticles by improving mechanical properties, thermal stability and flammability of rubber nanocomposites.

Thermal Stability Of

The blends of ethylene vinyl acetate (EVA) and thermoplastic polyurethane (TPU) were prepared by means of blending. The mechanical properties of EVA/TPU blends and thermal stability of the extrudates were investigated. The results show that the toughness of EVA/TPU has been improved after adding TPU into EVA, and doesn’t affect the thermal stability of material.

Eva Copolymer

An elastic co-film with excellent mechanical properties and adhesiveness, as well as good thermal conductivity, was fabricated based on the composition of a thermal-conductive alumina and ethylene vinyl acetate (EVA) copolymer. Thermal conductivity of the co-films with various particle sizes, amount, surface properties, and so on of alumina were investigated by the laser scattering method. The SEM results showed that the co-film with 16% (volume fractions) of submicron alumina in EVA copolymer had a good interface binding.

Nanocomposite foams based-on ethylene octene copolymer (POE)/ethylene vinyl acetate (EVA) copolymer were prepared by melting of POE/EVA with organic montmorillonite (OMMT) by pressurized curing at high temperature. The cellular microstructure of the foamed samples was observed by scanning electron microscope. The effects of OMMT on the cellular structure and mechanical properties of the POE/EVA/OMMT nanocomposite foams were investigated. It was found that OMMT played an important role in affecting the microstructure. Comparing with POE/EVA foam the nanocomposite foams with the addition of 1-3 phr OMMT showed smaller cell size and the structure uniformity of foams was improved. The density of POE/EVA/OMMT nanocomposite samples was lower obviously, meanwhile the mechanical properties of the foamed samples was enhanced.
