摘要
对Nano-SiO2进行两次表面处理,然后进行原位聚合制备聚酰胺酸/Nano-SiO2悬浮液,涂膜并热亚胺化得到PI/Nano-SiO2杂化膜。对Nano-SiO2的表面处理效果进行评价,对聚酰胺酸/Nano-SiO2悬浮液的稳定性、PI/Nano-SiO2杂化膜的性能进行测试。结果表明:Nano-SiO2的二次表面处理均为化学键合;聚酰胺酸/Nano-SiO2悬浮液稳定时间达到60 d,并获得了性能优异的PI/Nano-SiO2杂化膜。
Nano-SiO2 was surface treated twice, then polyamide acid/nano-SiO2 suspension was prepared using in-situ polymerization, finally, the thermal imidization was used to get PI/nano-SiO2 hybrid films. The effect of surface treated modification of nano-SiO2 was evaluated. The stability of polyamide acid/ nano-SiO2 suspension and the performance of PI/nano-SiO2 hybrid films were investigated. The results showed： all the twice surface modifications of nano-SiO2 were chemical bond; The stabilization time of polyamide acid/nano-SiO2 suspension reached to 60 days and the PI/nano-SiO2 hybrid films with excellent performances were acquired.
