Processing method for water soluble polymeric materials

摘要

Embodiments of the invention are directed to a method of forming a film of an insoluble conjugated polymer (CP) by deposition of an ionic CP from aqueous solution and converting the ionic CP to the insoluble CP. The ionic CP can be the salt of a carboxylic acid, sulfonic acid, phosphonic acid, boronic acid, amine, imine, phosphine, thioether, or complexed bidentate or polydentate ligand. The insoluble CP film can be used with an aqueous electrolyte solution for use as: an electrochromic film; charge injection layer for a solar cell, LED, and FET; conventional paints; supercapacitor; battery; electronic paper; anti-static coating; transparent conductor; sensors; anti-microbial coating; adhesive; RFID; or memory system.

主权项

1. A pi-conjugated polymer (CP) film, comprising an insoluble CP swollen by and/or contacting an aqueous electrolyte and being effectively free of any organic solvent, wherein the CP comprises repeating units having at least one side chain having a basic functionality and wherein the film can be dissolved by addition of an acid but not a base.
