摘要
采用1-氯萘溶液溶解聚苯硫醚(PPS),将富勒烯(C60)分散到PPS的1-氯萘溶液中,通过溶剂蒸馏和萃取分离,制得PPS/C60复合材料,通过熔融纺丝法制备PPS/C60复合纤维,研究了复合材料及其复合纤维的结构与性能。结果表明:PPS/C60复合材料中C60质量分数小于4%时,能够实现C60均匀分散于复合材料中;与机械混合相比,溶液分散法制备的复合材料C60分散更均匀;C60添加质量分数为4%时,PPS/C60复合纤维的断裂强度达到最高为3.07 c N/dtex,与PPS纤维相比,PPS/C60复合纤维的断裂强度提高了38%;C60与PPS发生π-π共轭作用,使复合材料的力学性能得到提高。
A polyphenylene sulfide/fullerene （PPS/COO） composite was prepared by dissolving PPS and dispersing C60 in 1- chloronaphthaline solution prior to solvent evaporation and extraction separation and was spun into PPS/COO composite fiber by melt spinning process. The structure and properties of PPS/C60 composite material and composite fiber were studied. The results showed that C60 could uniformly disperse into the PPS/COO composite at the mass fraction below 4% ; as compared with mechani- cal mixing method, solution diffusion method produced the composite material with more uniform C60 dispersion; the PPS/C60 composite fiber had the breaking strength maximum of 3.0 cN/dtex, 36% higher than that of PPS fiber, as the mass fraction of Coo was 2% in the composite; and the π-π conjugation occurerd between C60 and PPS and helped improve the mechanical proper- ties of the composite.
