Study on Water-resisting Photopolymer holographic recording material

We explored the reaction mechanism of the dual-wavelength water-resisting photopolymer. The photosensitive material which was sensitive to red and green light was synthesized, using the complex photo sensitizer. The photosensitivity was improved and the scope of the photosensitive spectrum was broaden. We also studied the influence of the ingredient on the holographic performance of the polymeric material. Further studies on the influence of the solution preparation on the quality of the hologram was made, too. The appropriate exposure time and disposal way were obtained through experiments. The experimental result indicates that this hologram of the dual-wavelength water-resisting photopolymer is damp-proofing and non-active. It is easy to preserve in any environment. It needn't chemical treatment to manufacture hologram applying this prescription. The diffraction efficiency would be increased obviously by heating. Providing ideal storage material to the manufacture of the holographic element, the prospect of the appplications would be more extensive.
