Abstract:
In a process for the preparation of a static dissipative material, the steps comprising:(a) providing a solid substrate material formed of a thermoformable polymeric matrix of low electrical conductivity;(b) contacting said substrate material with a dispersion of an aniline-based monomeric or oligomeric conductant comprising a substituted aniline constituent functionalized with at least one substituent selected from the group consisting of an ionic group, an alkoxy group, and an aryloxy group in a lipophilic or amphophilic solvent;(c) maintaining said dispersion in contact with said solid substrate material for a period sufficient to permit at least partial infusion of said aniline-based conductant into said polymeric matrix;(d) subsequent to step (c), subjecting said solid substrate material containing the infused aniline-based conductant to an oxidizing environment for a period of time sufficient to provide a substrate material of enhanced electrical conductivity.
