摘要

采用溶胶-凝胶和原位自金属化相结合方法制备聚酰亚胺（PI）/二氧化硅（SiO2）/银（Ag）三元复合薄膜

通过红外（FTIR）、透射电镜（TEM）、动态粘弹谱仪（DMTA）等系统地考察了热处理过程中杂化薄膜结构形态变化以及SiO2含量对金属银向基体表面迁移情况和杂化薄膜各种性能的影响.实验结果表明

在热处理过程中可以同时完成聚酰胺酸的亚胺化、SiO2粒子的形成及银的还原

并且可以通过改变热处理温度和时间或改变SiO2含量来控制银粒子向聚合物基体表面的迁移.

Abstract

Polyimide/silica/silver hybrid films were prepared via the combination of sol-gel method and in situ single-stage self-metallization technique.The structure of polyimide films in the thermal curing process and the influence of silica content on the transfer and aggregation of silver particles to the surface of hybrid films were investigated.Films were characterized by transmission electron microscopy

dynamic mechanical thermal analysis

Fourier transform infrared spectroscopy

ultraviolet visible spectroscopy and mechanical measurements.The results indicated that there was no degradation of polyimide matrix after the formation of silica and silver particles.Silica acted as the nucleus for the silver particles.With increasing the content of silica

more and more silver particles keep in the hybrid films instead of transferring onto the surface of the hybrid films

and the reflections of hybrid films decreased gradually.
