    Abstract: The present disclosure provides polyanilines, articles thereof, and methods of forming polyanilines. In at least one aspect, a polyaniline has a thermal stability of about 100° C. or greater, a weight average molecular weight (Mw) of from about 50,000 g/mol to about 150,000 g/mol and a molecular weight distribution (Mw/Mn) of from about 1 to about 5. In at least one aspect, a film includes a polyaniline, the film having a hydrocarbon content of about 1 wt % or less, based on the total weight of the film. In at least one aspect, a method includes introducing an emulsion of an aqueous solution of an aniline and an alkyl-substituted aryl sulfonic acid having 1 wt % or less of hydrocarbon content into a flow reactor, the flow reactor having a length of tubing having an inner diameter. The method includes polymerizing the monomer within the tube to form a polyaniline.

    Abstract: The present disclosure provides compositions, articles thereof, and methods of forming compositions. In at least one aspect, a composition includes (1) an epoxy, (2) an amino or amido hardener, (3) a polyaniline, (4) a dopant selected from a triazolyl, a thiazolyl, a quinolinyl, a salicylate, a benzoate, a glycolate, a phosphate, a sulfonate, or combination(s) thereof; and (5) a pigment selected from titanium dioxide, silica, talc, mica, aluminium stearate, or combination(s) thereof. The polyaniline+dopant comprises 6 wt % or less, by total volume of the composition. The present disclosure provides substrates having a composition disposed thereon. In at least one aspect, a method includes introducing an acid form of a polyaniline to a hydroxide to form a polyaniline hydroxide. The method includes introducing a dopant to the polyaniline hydroxide to form a doped polyaniline.
