摘要
选用 5种不同种类的偶联剂对二氧化钛纳米粒子进行了表面修饰 ,通过离心沉降分光光度法对上述体系在乙二醇中的分散性进行了对比表征 ,同时讨论了此体系在聚酰胺中的分散性能。结果表明 :适当的表面修饰有利于纳米二氧化钛在聚酰胺中的分散 ,而处理量为
Titanium dioxide nano particles were treated by five kinds of coupling agents on the surface. The dispersion behavior of titanium dioxide nano particles in ethylene glycol and polyamide was compared and characterized by centrifugal sedimentation spectrophotometric measurement. The results showed that proper surface treatment was helpful to the dispersion of titanium dioxide nano particles in polyamide, and lactic acid titanium gave best treating effect with the amount of 3%.
