An epoxy-imidazole resin system was used to form an anisotropic conducting film (ACF) for electronic equipment applications. Cationic cure of epoxy resins is very rapid and has shown potential in significant industrial processes which require fast reaction rates. In this study, benzyltetrahydrothiophenium hexafluoroantimonate, 1-(p-methoxybenzyl)tetrahydrothiophenium hexafluoroantimonate, benzylphenyl methyl sulfonium hexafluoroantimonate, and benzyl p-hydroxyphenyl methyl sulfonium hexafluoroantimonate were synthesized, and were used as latent thermal initiators for epoxy resins. The curing behavior of these sulfonium salts to epoxy resin was examined using DSC. The curing times were estimated at 150 ℃ and 180 ℃ using an indentation method. The reaction rate of these sulfonium salts were compared with other curing agents such as imidazole derivatives. |
