通过溶液共混法成功制备了氧化石墨烯/壳聚糖纳米复合材料. 透射电镜(TEM)结果表明, 氧化石墨烯纳米粒子在壳聚糖基体中分散良好. 拉伸实验结果表明, 随氧化石墨烯含量的增加, 氧化石墨烯/壳聚糖纳米复合材料的杨氏模量和拉伸强度均显著改善, 加入4 wt%的氧化石墨烯能够使纳米复合材料的杨氏模量和拉伸强度分别提高123%和117%|但另一方面, 却也在一定程度上使复合材料的断裂伸长率或韧性下降.

Chitosan/graphene oxide nanocomposites were prepared by solution blending method. TEM observations showed that the graphene oxide (GO) was well dispersed in chitosan matrix. By incorporating GO into chitosan, both tensile strength and modulus of the nanocomposites were significantly increased due to the fine dispersion of GO and strong interfacial interactions between GO and the chitosan matrix, while their elongation at break decreased to certain extent.

Key words: graphene, chitosan, nanocomposites
