Formation of dielectric films by ultraviolet photolysis of several organic monomers

Abstract

The ultraviolet photopolymerization of several simple unsaturated organic compounds has been studied with respect to the formation of a dielectric film on metallic film surfaces. The monomers gave films which were used as the dielectric medium in a number of test capacitors. Photopolymerization was carried out at a monomer partial pressure of a few rum Hg, the light source being a medium-pressure Hg arc. The test capacitors were made on a glass substrate by evaporating a Pb film, photopolymerizing the monomer to produce a dielectric film on the metal surface, and then evaporating a second Pb film.
