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.
