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。
Graphene oxide (GO) was prepared by natural graphite as raw material and modified by HUMMERS ’method. GO / PBS composites were prepared by in-situ composites Its performance was studied. The results show that the addition of proper amount of GO can accelerate the crystallization rate of GO / PBS composites more effectively. The addition of GO improves the mechanical properties and the rate of enzymatic degradation of GO / PBS composites. With the addition of GO, Crystal size decreases and GO functions as a nucleating agent.
