The oligomers were evaluated as resins for water-based UV curable coating. The rheology of the two oligomers' aqueous so-lutions was investigated in terms of solid fraction, pH dependence, and temperature dependence. The solutions were found to be Newtonian fluid showing rather low viscosity even at high solid fraction of 0.55. The drying process of the coatings and the properties of the cured coatings were studied by comparing them with water-dispersed UV-curable polyurethane methyl acrylate. It was evident that the water-soluble coating dried more slowly; and that the overall properties were inferior to those of the water-dispersed coating.展开更多

Ever-increasing environmental corsiderations make the processing of polyanilines shift from toxic organic solvent-based system to eco-friendly water-based system. The present paper reviews the synthesis of water-borne conducting polyanilines, and possible applications are discussed including supercapacitor electrode material, metal free corrosion protection coating, lithium oxygen battery cathode material and ultraviolet curable resin.展开更多
