Chitosan coatings ionically cross-linked with ammonium paratungstate as anticorrosive coatings for zinc
European Polymer Journal(2019)
摘要
•Zn plates were coated with ammonium paratungstate (PTA) impregnated chitosan (Chit)•PTA showed significant accumulation in Chit and ionically crosslinked it.•Anticorrosive properties were assessed with different methods.•The Chit-PTA coating provided good protection with 98% inhibition efficiency.•Chit-PTA coating can be applied for the temporary protection of zinc.
