摘　　要：将不同用量的纳米晶纤维素(NCC)与聚乙醇酸微波熔融聚合制备复合材料;并对其进行DSC、XRD、FTIR性能测试,得出:随着纳米晶纤维素含量的增加,能有效提高复合材料的玻璃化温度、降低熔点及分解温度、略微降低结晶度、提高拉伸强度,其中PGA-NCC-20性能较优.This paper describes the producing process of the composite materials of different amounts of nanocrystals cellulose（NCC）and poly glycolic acid（PGA）through microwave melt condensation polymerization.It also includes the performance test of DSC,XRD and FTIR on the composite materials and its results which show that with the increasing amount of NCC,the glass temperature of composite material is effectively raised,the melting point and decomposition temperature reduced,the crystallinity slightly reduced and the tensile strength improved,and PGA-NCC-20 have a better performance.
