Outline of Final Research Achievements

Because the surface chemical activities of both glass and fluoropolymer plastic films are lower, it is difficult to activate the surface, make it hydrophilic, and realize adhesion between them. A hybrid adhesive comprising these materials will be a promising new material. This study focuses on achieving high adhesive strength between fluoropolymer plastics and glass, realizing new functional properties at the adhesion interface, and clarifying their functional properties, using a plasma hybrid process. This study is the first to show highest adhesive strength of 3 N/mm in the adhesion of fluoropolymer plastic (PTFE). It is confirmed that hydrophilic functional groups, which improve the adhesion, are generated, and molecular-level firm adhesion to fluoropolymer is achieved.
