Abstract
A method for the surface modification of objects made from polyvinylidene fluoride by dehydrofluorinated of the surface of the objects. The dehydrofluorination is carried out with an etching solution which, in addition to a strong basic compound and a swelling agent and/or solvent for polyvinylidene fluoride, contains an auxiliary agent for the homogenization of the etching solution. The effect of etching is supported by an adhesion promoter. High resistance to shearing and good tough-elasticity in composite structure and laminates is achieved.
