纳米氧化石墨烯/聚丁二酸丁二醇酯复合材料的制备与性能

摘要

以天然石墨为原料,利用改进的HUMMERS'法制备了氧化石墨烯(GO);采用原位复合方式制备了纳米氧化石墨烯/聚丁二酸丁二醇酯(GO/PBS)复合材料,并对其性能进行了研究.结果表明:适量GO的加入能更有效地加快GO/PBS复合材料的结晶速度;GO的加入,提高了GO/PBS复合材料的力学性能和酶降解速率;随着GO添加量的增加,复合材料晶体尺寸减小,GO起到了成核剂的作用.%The graphene oxide(GO)was prepared by the modified Hummers'method and nano graphene oxide/poly(butylene succinate)(GO/PBS)composites were synthesized via in situ compound technology,and its proper-ties were studied.The experimental results showe that a suitable content GO can accelerate the crystallization process of GO/PBS composite.A certain amount of GO can improve the mechanical property and increase the speed of enzyme degradation.Otherwise,the crystal size of composites modified by inorganic nanoparticles is reduced,GO serves as an effective nucleating agent for the crystallization of GO/PBS.
