Polymer compositions, polymer films, polymer gels, polymer foams, and electronic devices containing such films, gels and foams

1. A method for making a polymer composition, comprising:

stirring a solution or dispersion of an electrically conductive polymer in a liquid carrier, and

adding an ionic liquid to the solution or dispersion of the electrically conductive polymer in the liquid carrier while stirring the solution or dispersion of the electrically conductive polymer in the liquid carrier;

wherein:

(a) the electrically conductive polymer comprises, based on 100 parts by weight of the electrically conductive polymer:

(i) from about 20 to about 50 parts by weight of one or more electrically conductive polymers comprising poly(3,4-ethylenedioxythiophene), and

(ii) from about 50 to about 80 parts by weight of one or more water soluble polymeric acid dopants comprising a poly(styrene sulfonic acid) dopant, and

(b) the ionic liquid comprises 1-ethyl-3-methyl-imidazolium tetracyanoborate.

2. A method for making a polymer film, comprising:

(A) forming a layer of a polymer composition, said polymer composition comprising

(a) a liquid carrier,

(b) one or more electrically conductive polymers dissolved or dispersed in the liquid carrier, said electrically conductive polymer comprising, based on 100 parts by weight of the electrically conductive polymer:

(i) from about 20 to about 50 parts by weight of one or more electrically conductive polymers comprising poly(3,4-ethylenedioxythiophene), and

(ii) from about 50 to about 80 parts by weight of one or more water soluble polymeric acid dopants comprising a poly(styrene sulfonic acid) dopant, and

(c) one or more ionic liquids dissolved or dispersed in the liquid carrier, said one or more ionic liquids comprising 1-ethyl-3-methyl-imidazolium tetracyanoborate, and

(B) removing the liquid carrier from the layer.
