| 摘 要： | 用低折射率的含氟共聚物为光致聚合物全息材料的成膜物,以增加全息记录材料折射率的空间可调制程度。用溶液聚合法合成了低折射率的水溶性甲基丙烯酸2,2,3,3-四氟丙酯-甲基丙烯酸共聚物(折射率为1.441),以该共聚物为成膜物质,丙烯酰胺为单体、亚甲基蓝为光敏染料、三乙醇胺为引发剂配制了光致聚合物薄膜;经过对光致聚合物组成构成的优化,在空间分辨力为1580lp/mm时,光致聚合物薄膜的灵敏度约为19 mJ/cm2,衍射效率可达93%,两者均优于以聚乙烯醇(PVA)为成膜物质的光致聚合物材料。 |

| Abstract: | Fluoro-containing polymer with low refractive index was used as the film-forming substance photopolymer holographic material to increase the spatial modulation range of its refractive index.Water soluble,fluoro-containing polymer with low reflective index derived from the copolymers of 2,2,3,3-tetrafluoropropyl methacrylate and methacrylic acid was prepared.The above polymer with low reflective index was used as the film-forming component,together with acrylamide as monomer,methylene blue as light-sensitive dye and triethanol amine as photo-initiator,for the preparation of photopolymer films for holographic recording.The photopolymer with optimized composition exhibited high sensitivity of 19 mJ/cm2 and high diffraction efficiency of 93% at spatial resolution of 1580 lp/mm,better than that with water soluble polyvinyl alcohol(PVA) as the film-forming substance. |
