Polymerization of acrylamide compounds onto Fe plates: An alternative route for applying polymer coatings

Abstract

AbstractAcrylamide and some of its derivatives were polymerized onto the surface of Fe plates by causing a slight corrosion of Fe to Fe2+ in the presence of perdioxy compounds. In water within a suitable pH range, the acrylamide monomers are likely to store at the metal–solution interface and to absorb on the iron surface. Thus, the polymerization takes place in situ, leading to the formation of uniform film coatings; the presence in the solution of a radical inhibitor imparts considerable stability to the bulk of the system. The dependence of the polymerization kinetics on several variables such as pH, monomer concentration, and peroxide concentration has been determined, and some characteristics of the resulting coatings were investigated.
