제목 Preparation of aromatic diacrylates containing phosphine oxide moiety in organic-inorganic sol-gel matrix for holographic recording
초록 The photopolymerizable films of aromatic diacrylic monomer containing phosphine oxide moiety in organic-inorganic sol-gel matrix were successfully photopolymerized by a 532 nm laser. The rate of photopolymerization and conversion of double bond in acrylic monomer were monitored by photo-Infrared spectroscopy (photo-IR) and photo-differential scanning calorimetry (photo-DSC). The amounts of a precursor of sol-gel solution and acrylate monomers were optimized to prepare the photopolymer films containing high diffraction efficiency. Fabricated photopolymer films could be thicker than 200 μm and their holographic recording achieved high diffraction efficiency (>93%) and low shrinkage (<0.5%). Grating image of the photopolymerized film and application to 3D recording media are in progress.
