Abstract

The present invention relates to a kind of photopolymer holographic recording material sensitive to green light and its preparation method. It is a dry photopolymer film, containing polyvinyl alcohol as film-forming material, acrylamide and methylene diacrylamide as monomers, erythrosine B as initiator and triethanolamine as coinitiator. Its preparation process includes the following steps: firstly, dissolving polyvinyl alcohol in distilled water to obtain aqueous polyvinyl alcohol solution with weight ratio of 10%, adding triethanolamine dissolved in distilled water to the aqueous polyvinyl alcohol solution, further adding erythrosine B crystal dissolved in distilled water, and adding acrylamide and methylene diacrylamide crystal to obtain photopolymer sol, pouring the above-mentioned sol on a flat plate, ageing and volatilizing water content so as to obtain the photopolymer dry film, its diffraction efficiency can exceed 90%, and it is specially applicable to optical hologram storage.

Description

Technical field: [0001] The invention relates to a photopolymer holographic recording material sensitive to green light and a preparation method thereof. The materials of the invention are especially suitable for optical holographic storage. Background technique: [0002] Optical holographic storage is a kind of mass storage that can not only write / read in parallel, improve data transmission rate, but also increase storage capacity. It has high storage capacity, very high data transmission rate, fast access time and high redundancy. The advantages such as redundancy can solve the inherent shortcomings of magnetic storage technology such as small capacity and bit-by-bit access, so it has become the leading direction of the development of computer storage technology today. The application of holography depends largely on the availability of suitable materials. Different recording media such as silver halide photoresists, dichromated gelatins, thermoplastics and photopolymers...
