Synthesis and characterisation of nano‐alumina hybrid polyimide films

Abstract

Purpose

The purpose of this paper is to synthesise and characterise nano‐alumina hybrid polyimide (PI) films.

Design/methodology/approach

PI nano‐composite films containing definitive contents of Al₂O₃ were prepared by the sol‐gel process of aluminum isopropoxide in the N, N′‐dimethylacetamide solution of polyamide acid. The films were characterised by Fourier transform infrared spectroscope, atomic forced microscope, and X‐ray fluorescent spectroscope (XRF). The thermal stability of the composite films was tested by TG.

Findings

PI nano‐Al₂O₃ films were prepared by the sol‐gel method. The XRF is an effective way to detect the inorganic phase of the composite films and measure the content of nano‐Al₂O₃.

Research limitations/implications

There are seldom reports about the PI composites containing Al₂O₃ through sol‐gel process.

Practical implications

PI has been widely used in the fields of aviation micro‐electron and less costly dyes.

Originality/value

Improved electricity insulation property of the PI films. Al₂O₃ particles were distributed homogeneously in the PI in nano‐scale by means of sol‐gel process.
