Hybridization of epoxy resin with a layered titanate and UV light durability and controlled refractive index of the resulting nanocomposite

A layered titanate-epoxy nanocomposite was synthesized by the reaction of a layered titanate modified with glycidyl and octadecyl groups and an epoxy resin followed by curing. The nanocomposite exhibited durability toward UV light compared with the pristine epoxy resin. Moreover, the refractive index (at 598 nm) of the nanocomposite was controlled in the rage of 1.51–1.53 by the added amount (0.00–0.04 mass%) of the organically modified titanate.
