通过氧化法制备了氧化石墨烯(GO),将GO与壳聚糖(CS)混合制备了GO/CS复合材料,并通过 FT-IR、XRD、TGA和力学实验对其结构、热力学稳定性及力学性能进行测试。测试结果表明,GO被成功制备;GO上的—COOH与CS上的—NH2发生酰胺反应生成—NHCO—,形成较强的界面结合力,GO的加入改善了CS的热稳定性,并且拉伸强度和杨氏模量均有所提高。
Graphene oxide(GO) was prepared by oxidation method,and prepared GO/chitosan(CTS) bio-based composite by mixing GO withCTS.Its structure and thermodynamic stability were tested through IR,XRD,TGA.And the mechanical properties were tested.GO test results shown that GO was successfully prepared.Composite material test results shown that —COOH on GO reacted with —NH2 on CTS to form —NHCO— which was a strong interface bond.The addition of GO improved the thermal stability of CTS,and improved the tensile strength and Young's modulus.
