Abstract

Electroconductive and reflective metallized polyimide films have been prepared by heterogeneous chemical modification of polyimide surface. By carrying out the chemical reactions in situ in the modified layers of polyimide surface, a metal phase strongly impregnated into the polyimide surface is obtained. The steps of chemical modification have been studied on the model compound – poly(amic acid) on the basis of isophthaloylchloride and methylenedianthranilic acid which forms insoluble sodium or potassium poly(amicacid) salts (polyamate). Metallization of Kapton HN &amp; JP (from DuPont) and Upilex S (from Ube) films<br />has been carried out and the films have been characterized by X-ray diffraction (XRD), X-ray fine diffraction (XRFD), measurements of reflectivity in the visible range and surface resistivity at elevated temperatures. It is shown that reflectivity coefficients of silvered films are 90-92% and surface resistivity is about 0.5 Ω/sq.

Highlights

One of main directions of search for new materials with specific physical properties is metallization of polymer films
In this work we present formation of a metal phase by carrying out in situ chemical reactions in modified polyimide films, as well as results of investigation of their structure and physical properties
One of the main chemical modification routes is hydrolysis of polyimide followed by exchange of K+ ions by Pd2+ cations

Summary

Introduction

One of main directions of search for new materials with specific physical properties is metallization of polymer films. In this work we present formation of a metal phase by carrying out in situ chemical reactions in modified polyimide films, as well as results of investigation of their structure and physical properties. In order to exclude the effect of surface morphology and polyimide: poly(amic acid) ratio of different films sides during hydrolysis process, we have taken more hydrolytically stable PAA2 film which can be considered as a model compound of poly(amic acid) (PMDA/ODA).
