Abstract
Coated substrates include a metal substrate and a polytriazole polymer applied to a surface of the metal substrate. The polytriazole polymer may include substituted phenyls, substituted benzyls, or both substituted phenyls and substituted benzyls. The substituted phenyls and the substituted benzyls may be independently substituted with hydrogen, bromo, fluoro, chloro, iodo, hydroxy, methyl, trifluoromethyl, dimethylamino, tert-butyl, carboxyl, triphenylmethyl, tris(4-fluorophenyl)methyl, tris(4-methylphenyl)methyl, (4-hydroxyphenyl)diphenylmethyl, and difluoromethoxy groups. The polytriazole polymer may have a degree of polymerization from 50 to 400.
Claims20
