제목 Characterization of PET/A-zeolite nanocomposites by in-situ polymerization
초록 Poly(ethylene terephthalate) (PET) is a thermoplastic polyester widely used in the manufature of high-strength fibers, photographic films, and soft-drink bottles because of its good mechanical properties with low cost. Zeolites are microporous crystalline aluminosilicates, composed TO4 tetrahedra (T=Si, Al) with O atoms connecting neighboring tetrahedra.1 Zeolites have potential applications such as catalysts, adsorption agents, ion-exchange resins and so on. Recently, Organic-inorganic nanocomposites have attracted great interests since they frequently exhibit unexpected hybrid properties synergistically derived from the two components.2 A-zeolite having a Si/Al ratio 1, sodium ions, and a pore size larger than 4Å was therefore used in the present study as nanocomposite fillers of PET matrix. The objective of this study is the hope that PET molecular threading into well-dispersed A-zeolite will provide such intimate interactions between PET chains and A-zeolite resulting in a novel reinforcement effects.3 Thus, Poly(ethylene terephthalate) (PET) nanocomposites containing (0.5-2 wt%) A-zeolite were prepared by in-situ polymerization. Then, Thermal, rheological properties, and crystallization behavior were investigated.
