无机纳米杂化聚酰亚胺薄膜的研究进展

Research Advance of Inorganic Nanoparticles Hybrid Polyimide Film

无机纳米杂化聚酰亚胺复合薄膜因无机填料在聚合物基体中纳米尺度的分散以及与基体间强的化学结合而具有较常规聚酰亚胺薄膜材料更优异的力学性能、热稳定性能、高绝缘性能及耐电晕性能等。依据国内外聚酰亚胺纳米杂化薄膜材料的最新研究情况,重点综述了SiO2/Al2O3、SiO2/Ti2O3、SiO2、TiO2、Al2O3、SiC、MMT等纳米杂化聚酰亚胺薄膜的研究进展,表明其是一种性能优异、具有广泛应用前途的有机-无机纳米复合材料,但尚存在许多需进一步深入研究的问题。

Owing to the dispersion of inorganic filler in the matrix of inorganic nanometer hybrid polyimide film and the strong chemical interaction between the filler and the matrix, the hybrid composite film has better mechanical, thermal, higher electrical insulating and corona-resistant properties. In this paper, some recent research development on SiO2/Al2O3,SiO2/Ti2O3,SiO2,TiO2,Al2O3,SiC and MMT inorganic nanometer hybrid polyimide film was reviewed. It was pointed out that inorganic nanometer hybrid polyimide film has broad application prospect, and deep research on the composites needs to be done.
