Patent ID: 8198396

Claim:
A method consisting of forming an admixture of a solvent selected from the group consisting of dimethyl sulfoxide (DMSO), dimethyl formamide (DMF), N-methylpyrrolidinone (NMP), tetramethyl urea, pyridine, m-cresol, phenol, dimethylacetamide, n-cyclohexylpyrrolidinone, 80% aqueous acetic acid, pyrrolidinone, N,N′ dimethyl propyl urea, benzyl alcohol, and a combination of NMP/m-cresol; an additive selected from the group consisting of adipic acid, azelaic acid, benzoic acid, citric acid, dimer acid, epoxy, fumaric acid, glycerol, lauric acid, linoleic acid, maleic acid, sebacic acid, stearic acid, succinic acid, terpentines, siloxanes, polysiloxanes, ethylene glycols, polyethylene glycols, polyesters, sucrose, myristic acid, oleic acid, palmitic acid, paraffin, phosphoric acid, phthalic acid, ricinoleic acid, tartaric acid, trimellitic acid, phosphonic acid, and polysilanes, poly-co-dimethyl propylamine siloxane said solvent in said admixture being different from said additive; and a polymer selected from the group consisting of a precursor to an electrically conductive polymer and an electrically conductive polymer, said precursor to said electrically conductive polymer being made electrically conductive by means of a doping reaction with an acid, said electrically conductive polymer and said doped polymer being selected from the group consisting of substituted and unsubstituted polyparaphenylene vinylenes, polyparaphenylenes, polyanilines, polythiophenes, polyazines, polyfurans, polypyrroles, polyselenophenes, poly-p-phenylene sulfides, polyacetylenes formed from soluble precursors, combinations thereof; said electrically conductive polymer and said doped polymer being soluble in said solvent, said electrically conductive polymer and said doped polymer not being substantially soluble in said additive in the absence of said solvent, said additive provides local mobility to said polymer to allow regions of said polymer to associate with one another to achieve a crystalline state; and partly removing said solvent, substantially leaving said additive therein as remaining additive, said remaining additive provides local mobility to said polymer to achieve said crystalline state thereby comprising a polycrystalline material, said polycrystalline material is characterized by a degree of crystalline regions and a degree of amorphous regions, said degree of crystalline regions and said degree of amorphous regions are selected by selecting the composition of said additive, and the amount of said additive; forming a film from said admixture, said film possessing isotropic conductivity.
