Evaluating the Adhesion Characteristics of Glowdischarge Plasma-polymerized Films by a Novel Voltage Cycling Technique
Many thin-film epoxy and polymeric coatings are available as electrical insulating materials. Most of these films exhibit excellent bulk electrical properties; however, their electrical insulting characteristics are compromised or diminished at interfacial boundaries when they are submerged in conductive solutions. the loss of insulative properties is generally associated with the loss of adhesion to the underlying substrate. the authors have developed a voltage cycling technique using a modified form of cyclic voltammetry to stress this interfacial region under accelerated end use conditions. It was found that this technique was preferable to conventional ones (i. e. , pull tests) in that the authors could observe the synergistic effects of water, ions, and electric fields on the rate of adhesive loss of the insulating films to their underlying substrates. Improvements in the adhesion of Parylene films to platinum substrates by the use of primer coatings of glow-discharge polymers is also verified by this technique.
