Synthesis and characterisation of nano‐alumina hybrid polyimide films

Synthesis and characterisation of nano‐alumina hybrid polyimide films 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 Al 2 O 3 were prepared by the sol‐gel process of aluminum isopropoxide in the N, N&vprime;‐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‐Al 2 O 3 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‐Al 2 O 3 . Research limitations/implications – There are seldom reports about the PI composites containing Al 2 O 3 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. Al 2 O 3 particles were distributed homogeneously in the PI in nano‐scale by means of sol‐gel process. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Pigment & Resin Technology Emerald Publishing

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 Al 2 O 3 were prepared by the sol‐gel process of aluminum isopropoxide in the N, N&vprime;‐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‐Al 2 O 3 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‐Al 2 O 3 . Research limitations/implications – There are seldom reports about the PI composites containing Al 2 O 3 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. Al 2 O 3 particles were distributed homogeneously in the PI in nano‐scale by means of sol‐gel process.
