Abstract

The effect of γ-ray and electron irradiation on the adhesion of gold films to PTFE has been ascertained. The film adhesion has been found to undergo a sharp increase at a γ-ray dose of 5 × 106 to 1 × 107 rads. Qualitative ‘Scotch tape’ tests also show an increase in adhesion when the films are irradiated with electrons (250 eV - 3 keV).

Examination of the interface region of very thin (∼ 20 Å) gold films on PTFE by X-ray photo-electron spectroscopy indicates the increase in adhesion results from radiolytic processes and consequent chemical interaction with the gold.
