We have studied the fabrication of planner polymer devices by using self-organization based on non-equilibrium phenomena. Honeycomb-patterned films from various kinds of functional polymers were prepared by casting polymer solutions under humid conditions. Water droplets were condensed onto the solution surface by evaporation cooling, and finally, the micro-porous polymer films were formed after complete evaporation of solvent and template water droplets. Polymer nano-particles were prepared by mixing a poor solvent into a polymer solution, and following evaporation of a good solvent, By using this method, various kinds of polymers including biodegradable, electron conductive, and electro-luminescence polymers were prepared. The particle size was controlled from tens nm to tens micrometer by changing the preparation condition (e.g. concentration of polymer solution, ratio between the poor solvent and polymer solution). Furthermore, we fabricated the hybrid structures of the honeycomb-patterned micro-porous film and functional nanoparticles by casting the water dispersion of nanoparticles onto the UV-Ozone treated honeycomb-patterned films. UV Ozone treatment change the surface properties of the honeycomb-patterned films from hydrophobic to hydrophilic. The polymer nanoparticles were embedded onto the pores of hoenycomb structures by capillary force.

我们研究了利用非平衡现象的自组织来制备平面聚合物器件。在潮湿条件下，通过浇铸聚合物溶液制备了各种功能聚合物的蜂窝图案膜。通过蒸发冷却将水滴冷凝到溶液表面，最后溶剂和模板水滴完全蒸发后形成微孔聚合物膜。通过将不良溶剂混合到聚合物溶液中，然后蒸发良溶剂来制备聚合物纳米颗粒。通过使用该方法，制备了各种聚合物，包括生物可降解聚合物、电子传导聚合物和电致发光聚合物。通过改变制备条件（如聚合物溶液的浓度、不良溶剂与聚合物溶液之间的比例）将粒径控制在几十nm至几十微米。此外，我们通过将纳米颗粒的水分散液浇铸到经UV-臭氧处理的蜂窝图案化膜上来制备蜂窝图案化微孔膜和功能性纳米颗粒的杂化结构。紫外臭氧处理改变蜂窝图案化膜的表面性质从疏水性到亲水性。聚合物纳米粒子通过毛细作用力嵌入蜂窝状结构的孔中。
