Adhesion of Plasma Polymerized Films (A Model Study on Water Sensitivity of Adhesion)

  • H. Yasuda

Abstract

Failures of coatings or thin polymer films applied to different kinds of materials, such as metals, ceramics, and polymers, due to the influence of water (liquid or vapor) are related to the affinity of water to the substrate surface and to the polymer coating. Therefore, there is no direct correlation between dry adhesive strength and wet adhesive strength. This situation can be demonstrated by using vacuum deposition of polymers by Parylene polymerization and/or plasma polymerization of organic monomers. Because of unique polymerization mechanisms, plasma polymers can be utilized to provide ultrathin primer coatings which adhere well to metals and ceramics and convert hydrophilic nature to more hydrophobic surface and improve the overall water resistivity of adhesion of coatings.
