Improved shelf-life stability of holographic photopolymer containing monomer stabilizer

Herein we present an environmentally robust photopolymer system containing monomer stabilizer and thereby can improve the shelf-life stability of conventional photopolymer media. In this report, we conducted systematic study of the radical scavenger effect on shelf-life time in terms of achievable diffraction efficiency of photopolymers as a function of storage time. Furthermore, the stability of photopolymerizable monomer was also discussed regarding to monomer conversion by FT-Raman analysis during the storage.

► We report an environmentally robust photopolymer system.
► The use of radical scavenger improved shelf-life stability of photopolymer.
► The holographic performance was studied upon storage time.
► Undesired dark-reaction was controlled during storage.
