合成了偶氮苯功能化液晶聚合物P3 AB 6Ac，并研究了其光致异构性和全息性。用差示扫描量热法和偏光显微镜对聚合物的液晶性进行了表征。该聚合物在溶液和薄膜中都表现出可逆的光致异构化。用线偏振和圆偏振的Ar ~+激光分别通过光掩模在旋涂聚合物薄膜的THF溶液中诱导出表面浮雕光栅。利用原子力显微镜研究了表面浮雕结构。用圆偏振Ar ~+激光辐照30 min，得到了表面调制深度为400- 500 nm的表面光栅。聚合物膜的记录期也被发现相当高，超过一年。
Liquid crystalline azobenzene functionalized polymer, P3AB6Ac has been synthesized and its photoisomerization and holographic properties have been studied. The liquid crystalline properties of the polymer were confirmed by differential scanning calorimetry and optical polarizing microscopy. The polymer showed reversible photoisomerization in both solution and in the film. Surface relief gratings were induced on the polymer films prepared by spin-coating from its solution in THF by the irradiation of linearly polarized and circularly polarized Ar+laser individually through photomask. The surface relief structures were investigated using atomic force microscopy. A surface grating with a surface modulation depth of 400–500nm was obtained by irradiation of circularly polarized Ar+laser for 30min. The period of record of the polymer film was also found to be considerably high, more than one year.
