Paper Abstract

Photopolymer films containing s-triazine (ST) methacrylic monomers were explored for holographic recording. Photofunctional s-triazine derivative having polymerizable group was synthesized starting from the reaction of a ST di-thiol derivative with methacryloyl chloride to give ST methacrylic monomer substituted with methylthio group (TRSM). ST methacrylic monomer substituted with ethylene oxy unit (TREGM) was synthesized from the reaction of a diamine substituted ST dichloride derivative with hydroxyl-ethyleneoxy methacarylate (HEMA). Photopolymer films prepared by mixing the s-triazine monomer with binder, additives, and photoinitiator were sensitive to a visible light and polymerized upon excitation with a visible laser. The optimization of holographic recording media was achieved by controlling the concentration and chemical structure of monomer composition in photopolymer films to control the diffusion and polymerization of monomer. The new photopolymer films containing ST methacrylic monomer substituted with ethylene oxy unit (TREGM) showed diffraction efficiency reaching ~ 90%. High diffraction efficiency and fast response for the photopolymer prepared from TREGM monomer were ascribed to the effective monomer compatibility with the binder to result in high optical clarity of the film.
