Refractive Index Control and Electron Beam Pulse Radiolysis of Transparent Polyimides

摘要

Refractive index change was induced by electron beam irradiation to transparent polyimides as large as 10~(-2).Active intermediates during the electron beam irradiation were determined by electron beam pulse radiolysis of several model imide compounds.Strong electron affinity of the transparent polyimides was one of the key factors for the reaction.
