摘　　要：为改善聚丁二酸丁二酯(PBS)的性能,分别以三苯基羟乙基溴化膦改性的蒙脱土(OMMT1)、十六烷基三苯基溴化膦改性的蒙脱土(OMMT2)为添加相制备了PBS复合材料,着重考察了改性剂结构对PBS复合材料性能的影响。微观结构表明,OMMT2较OMMT1在PBS基体中分布分散均匀。差示扫描量热(DSC)仪测试结果表明,PBS/OMMT2复合材料较PBS/OMMT1复合材料具有更高的结晶温度和熔融温度。动态流变结果表明,低频区PBS/OMMT2复合材料较PBS/OMMT1复合材料具有更高的储能模量、损耗模量和复数黏度。力学性能测试结果表明,PBS/OMMT2复合材料较PBS/OMMT1复合材料具有更高的缺口冲击强度、拉伸强度、弯曲强度和弯曲弹性模量。In order to improve the performance of poly(butylene succinate)(PBS),PBS composites were prepared respectively with organic montmorillonite(OMMT2)modified by cetyl triphenyl phosphonium bromide and organic montmorillonite(OMMT1)modified by triphenylhydroxyethyl phosphonium bromide as additive phase.The influence of modifier structure on the performance of PBS composites was investigated.The microstructure results show that OMMT2 is distributed on PBS matrix more evenly than that of OMMT1.The results of differential scanning calorimeter(DSC)show that PBS/OMMT2 composite has higher crystallization temperature and melting temperature than PBS/OMMT1 composite.The dynamic rheological results show that the PBS/OMMT2 composite has higher energy storage modulus,loss modulus and complex viscosity than PBS/OMMT1 composite in low frequency region.The mechanical properties test results show that the PBS/OMMT2 composite has higher notched impact strength,tensile strength,bending strength and bending modulus than PBS/OMMT1 composite.
