【摘要】 利用原位聚合法制得聚乙烯/壳聚糖(PE/CS)复合材料.IR、DSC和SEM等手段对催化剂负载机理和材料的性能进行了表征.结果表明:随着壳聚糖含量的提高,材料的热性能和力学性能下降.壳聚糖的质量分数控制在7.8%,材料表现出较好的综合性能;在负载的过程中,使用烷基铝对载体进行预处理会使所制备的复合材料的力学性能下降;复合材料的抑菌效果随壳聚糖质量分数的增加而提高.更多还原

【Abstract】 A novel polyethylene/chitosan composite material was prepared via in-situ coordinated polymeraztion.The mechanism of catalyst loading was studied by using FTIR.Thermol and mechanical properties of materials were tested by using DSC,SEM,FTIR.The results showed that the properties of composite materials decreased with the rising of chitosan content and dropping of loading content of Ti~4+;The materials have good antibacterial property.更多还原
