Preparation and Research of the Anticorrosive Coatings with Copper Ions-Polyaniline Loaded Montmorillonite

Montmorillonite intercalated polyaniline material was prepared by Situ polymerization method,the effects ofinitiator content, polymerization time, temperature and other parameters on the adsorption Cu2+of prepared material were discussed by single-actor method and the montmorillonite loaded copper ions-polyaniline was obtained. Finally an anti-corrosion coating was prepared with montmorillonite loaded copper ions-polyaniline as filler.The results showed that montmorillonite intercalated polyaniline had the best adsorption characteristics on Cu2+and its light transmission rate reached 100% when the montmorillonite was 2g, the initiator (ammonium persulfate) was 0.1g, the temperature was 80°C, and the polymerization time was 2h. The prepared anti-corrosion coating had good corrosion resistance and its hardness was 90, its adhesive force reached level 1 when mass fraction of filler was 10% in total.
