"核壳结构"粒子对PA6/SEBS-g-MA/PPO共混物的增韧作用
Toughening Effects of "Core-Shell" Particles in PA6/SEBS-g-MA/PPO Blends
摘要
Abstract
Blends of polyamide-6 (PA6)/styrene-ethylene-butadiene-styrene block copolymer grafted with maleic anhydride (SEBS-g-MA) /poly (phenylene oxide) (PPO) were prepared via melt blending, and toughening effects of PPO in PA6/SEBS-g-MA/PPO blends was discussed. The effects of PPO contents on the morphology and notched Izod impact strength of PA6/SEBS-g-MA/PPO blends were studied by scanning electron microscopy (SEM) and pendulum impact tests. Surface energies of PA6, SEBS-g-MA and PPO were measured by contact angle measurements, which were used to calculate interfacial tension between each other."Core-shell" particles with PPO (core) and SEBS-g-MA (shell) were formed in PA6 matrix driven by interfacial tension and spreading coefficient. Impact test results indicate that the "core-shell" particles play a key role in toughening PA6 blends. With the increase of PPO content within a certain range, the number of "core-shell"particles increases and the impact strength increases first and then decreases.关键词
