Novel water based coatings containing some conducting polymers nanoparticles (CPNs) as corrosion inhibitors

摘要

A new type of anticorrosive water-based paints containing some conducting polymers nanoparticles (CPNs) such as poly anisidine (PAns), poly toluidine (PTol) and their copolymer (CCPNs) have been prepared and evaluated. The CPNs and CCPNs have been synthesized via miniemulsion polymerization. The prepared materials have been characterized by GPC, FTIR, TEM and DSC. The prepared CPNs and CCPNs of different weight percentages (wt.%) have been incorporated into paint formulations. It has been found that the presence of the prepared CPNs and CCPNs in the paint formulations highly enhanced the resistance of the formed paint films against washability, weathering and corrosion.
