In this study we investigated five different types of organo-functional silanes containing vinyl, epoxy, amino, methacrylic and acrylic groups in the cationic polymerization of epoxide resin and studied their effects on epoxide adhesion strength to indium tin oxide (ITO) substrate via a pull test. The adhesion strength of epoxide resins was found to be in the order vinyl > methacrylic > acrylic > epoxy > amino. The silane containing vinyl group enhanced the adhesion strength, since it was able to promote free-radical polymerization. As to the silane containing amino group, it retarded the photo-polymerization of cationic photoinitiator in the resin and thus the lowest adhesion strength was observed. It was found that the resin sample containing 1 wt% of vinyl group silane possessed the highest adhesion strength of 91.42 kg/cm2 to ITO glass. An excessive amount of silane added in the resin generated too much H2O that diluted the concentration of resin and deteriorated the adhesion strength.
