Effect of organic-inorganic compound antioxidant on structure and properties of polyphenylene sulfide
摘要
Abstract
An organic-inorganic compound antioxidant(GO-sHP)was prepared through chemical grafting of GA-80 into graphite oxide(GO)sheets.The resultant GO-sHP was melt-blended with polyphenylene sulfide(PPS)by using a mi-cro-twin-screw extruder.The structure and properties of the obtained PPS blends were intensively analyzed.The results indicate that GO-sHP showed high thermal stability and could well be melt-blended with PPS.GO-sHP exhibited good compatibility with the PPS matrix and could be uniformly dispersed in the matrix without any agglomerations.The intro-duction of GO-sHP could promote the crystallization of PPS to improve its crystallinity.As the GO-sHP content in-creased,the crystallization temperature of PPS increased and its supercooling degree decreased.The introduction of GO-sHP improved the thermal stability of PPS,and its heat resistance temperature index increased with an increase in the GO-sHP content.The addition of GA-80 improved the tensile fracture strength of PPS significantly.After thermal oxidation treatment,pure PPS presented a decrease in the tensile fracture strength by 4.1%.However,the PPS blend containing 0.3 wt%GO-sHP showed a decrease in the tensile fracture strength only by 2.4%.关键词
