溶剂散逸自组装法制备具有电致收缩性能的聚苯胺/聚氨酯凹透镜阵列

以水珠为模板，采用溶剂散逸自组装法制备了表面具有特殊形貌的有序多孔膜. 以此多孔膜为模板制备了聚苯胺/聚氨酯（PANI/PU）的凹透镜阵列. 采用红外光谱（FTIR）和扫描电子显微镜（SEM）对界面聚合得到的PANI/PU纳米复合物的结构和凹透镜阵列的形貌进行了表征，研究了不同合成条件对纳米复合物导电性能的影响，并对PANI/PU凹透镜阵列的电学和光学性能进行了研究. 结果表明，PANI/PU凹透镜阵列同时具有导电性、电致收缩性和光衍射性质；其收缩率与外加电压成反比，而透光率与收缩率成正比.

Preparation of Electrostriction of PANI/PU Concave Lens Array by Solvent Evaporation Self-organization

Ordered porous membrane with specific morphology were prepared by solvent evaporation self-organization using water drops as the template. The polyaniline/polyurethane(PANI/PU) concave lens array was prepared by the above ordered porous membrane. FTIR and SEM were employed to study the structure of PANI/PU nanocomposite which was synthesized by interfacial polymerization and the morphology of the concave lens array. The effect of different synthesis conditions on the conductivity of PANI/PU nanocomposite were studied, and also discussed the electrical properties and optical performance of PANI/PU concave lens array. The results indicated that the PANI/PU concave lens array had electrical conductivity, while exhibited electrical contractility and the properties of light diffraction; the shrinkage of PANI/PU film is inversely proportional to voltage, and the transmittance is proportional to the shrinkage.
