Abstract
Plasma-polymerized coatings were prepared in a bell-jar-type reactor equipped with a magnetron system behind parallel aluminum electrodes using an a.c. source of frequency 10 kHz. Tetramethoxysilane, dimethyldimethoxysilane and hexamethyldisilane were used as monomers. Alkyd paint was coated on titanium plates onto which plasma polymer films had been deposited, to investigate the characteristics of the plasma-deposited films as adhesion promoters. The relationship between the adhesion strength for the paint and the conditions for the plasma polymerization was studied. The properties of the plasma polymers are dependent on the conditions of plasma polymerization manifested by two domains, namely the energy-deficient and the monomer-deficient regions. In the energy-deficient region, the differences due to the monomer structure can be clearly observed; however, in this region the adhesion of the plasma polymer film to the substrate metal is poor, and the plasma polymer does not serve as a good primer for the paint. In the monomer-deficient region (for this study a power input per unit mass of starting material of W/FM ≥ 1.7 x 109 J kg-1) improved adhesion of the paint is obtained; however, in this region the difference due to the monomer structure is found to be minimal. © 1984.
