Abstract:

首先用硫酸水解被囊动物海鞘制备海鞘纤维素纳米晶(TCNC),用TEMPO(四甲基哌啶氮氧化物)/NaBr/NaClO氧化体系将其表面的羟基氧化成羧基(TCNC-COOH),再以其作为基质,加入聚多巴胺包覆并还原的氧化石墨烯纳米粒子(PDA-rGO)作为填料,采用流延成膜的方式制备了一种可导电和生物降解的复合材料膜,并通过透射电镜(TEM)、傅里叶变换红外光谱(FT-IR)、X射线衍射(XRD)及热重分析(TGA)等测试表征基质和填料的形貌、结构、结晶度及热稳定性.力学性能结果显示,在TCNC-COOH中添加0.5%PDA-rGO后,复合材料的杨氏模量和拉伸强度分别增加85.7%和78.99%;添加1%PDA-rGO,材料的体积电阻率从7.6×10~9Ω·cm降低至7.7×10~5Ω·cm
