| 摘 要： | 在140℃，氮气保护的条件下，使L-丙交酯开环与凹凸棒石黏土（AT）表面上的（Si-OH）发生反应，生成的低分子量聚乳酸接枝到经过处理的凹凸棒石黏土上，然后将接枝凹凸棒石黏土与聚乳酸（PLA）景丁二酸丁二醇酯（PBS）进行熔融共混，制备PLA／PBS／凹凸棒石黏土（AT）复合材料．通过FTIR、SEM、力学性能测试及维卡软化测试仪对复合材料进行分析和袁征．实验结果表明，凹凸棒石黏土的最佳加入量为1．5％；PBS的加入可以大大提高PLA的韧性，当加入量为25％时，综合力学性能最佳．

| Abstract: | The L-lactide was reacted with Si-OH on attapulgite clay surface via a ring-opening under the protection of nitrogen at 140 ℃ to produce polylactic acid oligomers,which were grafted onto the treated attapulgite clay(AT),and then they melted blending with polylactic acid(PLA) and poly(butylene succinate)(PBS) to obtain PLA/PBS/attapulgite clay(AT) composites.They were analysed and characterized by means of FTIR,SEM,mechanical property testing and Vicat softening tester.The results showed that the best content of attapulgite was 1.5%.The addition of PBS could greatly improve the toughness of PLA;for best mechanical properties,the optimal amount was 25%. |
