摘要
Arolled mild steel wascoated byconductive polymers( polyaniline/ MMPand polyaniline/HCSA) andthenim mersedin hot water(50 ℃) fordifferenttimesforstudytheadhesion ofcoatings.It wasfound thatthe adhesion tendsto decrease over time. Thestudyshown that onebrittle and porous Fe3 O4 layer formed between conductive polymercoating and steelsub stratein a moistenvironmentand, asa result, decreased thecoating adhesions.
