In the present study, very small concentrations of CNCs and CNFs were melt-compounded into PLA using a solvent-free process where poly(ethylene glycol) (PEG) was used to disperse the nanoparticles in ...
目前,溶液浇铸法制备纳米纤维素/聚乳酸复合材料,常将纳米纤维素直接加入聚乳酸,导致制备的复合材料各项机械性能普遍降低。为了改善其机械性能,笔者采用聚乙二醇2000作为塑化剂处理纳米纤维素,制备聚乳酸/纳米纤维素/聚乙二醇三相复合材料。通过对复合材料的微观形貌观测,力学性能分析和热稳定性分析来确定聚乙二醇的影响机制。试验结果表明,添加2%～4%聚乙二醇2000的三相复合材料的拉伸强度、撕裂强度与断裂...
