| Outline of Final Research Achievements |
We have carried out theoretical studies of adhesion interactions of epoxy resin and metal surface, carbon surface, and glass surface using quantum chemical calculations, demonstrating that hydrogen bonding is a main factor for the adhesive interactions. In particular we considered effects of adsorbed water molecules on the adhesive surface. Our calculation models consist of epoxy resin of the bisphenol A type with hydroxylated alumina, carbon, and glass surfaces. Adsorbed water layers significantly weaken the adhesive forces.
