Aqueous polyaniline suspensions: Chemical oxidative polymerization of dodecylbenzene-sulfonic acid aniline salt

Add time:08/06/2019    Source:sciencedirect.com

Chemical oxidative polymerization of dodecylbenzenesulfonic acid aniline salt in water using ammonium peroxydisulfate as oxidant was found to give an homogeneous polyaniline suspension. An aqueous transparent and green uniform suspension containing polyaniline complexed and doped with dodecylbenzenesulfonic acid was obtained to show a typical emeraldine salt spectrum. The polyaniline suspension was quite stable without any precipitation for several months and could be diluted with water. Polyaniline recovered from the reaction mixture with addition methanol was characterized.
