Diverse Methods to Nanomanufacture Colloidal Dispersions of Polyaniline without Templates

Different methods which could be used to produce colloidal dispersions of polyaniline (PANI) nano-objects without templates are described. While the non-deterministic, different (nanospheres, nanofibers, nanobelts, nanorice, nanotubes, nanorods, nanodisks, etc.) can produced. Those most are: (i) solution polymerization with steric stabilizers (SPS) nanospheres, (ii) interfacial (IP) nanofibers and (iii) in presence additives (SPA) nanotubes. Oxidation aniline aqueous other shapes by controlling mass transport/concentration reactants, pH, oligomers/additives. The models proposed explain formation various discussed. Mechanochemical (MCP) or nanospheres aniline/oxidant ratio. PANI tunable sizes also produced nanoprecipitation (NPT) preformed from its solutions using an antisolvent. geometrical constraints small made high-molecular-weight rigid polymers conditions nanostructures affect intrinsic properties (conductivity, crystallinity, electroactivity). Selected technological applications manufactured as Based on reviewed work models, future lines proposed.
