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

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.

Ordered porous membrane with specific morphology were prepared by solvent evaporation self-or- ganization 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 con- cave 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 pro- portional to voltage, and the transmittance is proportional to the shrinkage.
