碩士 === 國立交通大學 === 材料科學與工程系 === 88 === In this thesis, we synthesize several kinds of high optical quality photopolymer based on PQ which is applied on holographic memory. Chemical analyses are performed to study on the recording mechanism. Based on these results, characteristics for holographic data storage are obtained. Our samples are prepared by dissolving 9,10-phenenthrenequinone (PQ,0.7%) and initiator azobisisobutyronitrile (AIBN,0.5%) in the purified Methyl methacrylate (MMA)、Methacrylic Acid 2-Hydroxyethyl Ester (HEMA)、Methacrylic Acid Ally Esteracrylate (MAAE) monomer. The solution is poured into different glass flasks to fabricate the samples in a variety of dimensions. The samples with different conditions concentration such as temperature ,time ,and process about the flasks making to polymerize monomer. Then, the samples are turned into solid blocks. Based on the principle of PQ molecules reacted with monomers one by one when exposured and different monomers with PQ will products different compounds. Analyzing of the optical exposed samples by using UV, TGA, GPC, FT-IR and NMR indicates that in our PMMA/PQ、PHEMA/PQ、PMAAE/PQ samples. By chemical analyzing ,we known what kind of the product will be formed and we suppose the reasonable models for optical storage mechanism about PMAAE/PQ and PHEMA/PQ. About holographic optical data storage characteristic ,we have performed diffraction efficiency. By induce different functional groups ,different diffraction efficiency we got. Response time decrease with monomer polymerized and the functional groups increase which is participated in reaction. The research of the effect of time and temperature to diffraction efficiency which is based on PMMA/PQ also show the good stability. It will have many good advantages for material which is used on holography optical data storage.
