研究了聚（3-烷基噻吩）凝胶等高导电性共轭聚合物凝胶的制备方法。导电聚合物凝胶的体积、颜色、形状和电导率随着温度、溶剂组成和掺杂水平的变化而急剧变化，这些变化取决于聚合物结构的阈值条件。结论是掺杂后导电聚合物凝胶中链间相互作用的改变导致了导电聚合物凝胶性能的变化。掺杂离子的扩散系数取决于凝胶的交联程度。这一观察结果被认为是传感器材料的重要特性。导电聚合物凝胶的体积不稳定性动力学取决于凝胶膜的溶剂种类、组成和均匀大小。已经讨论了这种依赖性的机制。导电聚合物凝胶的这种尺寸依赖动力学表明，小凝胶膜和纤维的集成应该是实现具有快速责任的执行器的有效方法。制备了一种由聚3-烷基噻吩凝胶和聚吡咯膜组成的双晶膜，并对其性能进行了研究。这种双晶片随着温度、溶剂、化学和电化学掺杂的变化而弯曲。通过优化工艺条件，提高凝胶致动器的性能。研究了双晶片的瞬态特性，发现了异常的瞬态现象。新的功能凝胶应用比例利用这一异常。这些结果为共轭导电聚合物凝胶的实际应用提供了重要的参考。

Preparation methods of a number of conjugated highly conducting polymer gels such as poly(3-alkylthiophene) gel have been investigated. Volume, color, shape, and conductivity of the conducting polymer gels change drastically upon change in temperature, solvent composition and doping level over the threshold conditions which depend on the polymer structure. Change in inter-chain interaction in the conducting polymer gels was concluded to result in these changes in properties of conducting polymer gels upon doping. Diffusion coefficient of the dopant ions depends on the degree of cross-linking of the gels. This observation is thought to be important characteristics as the sensor material.Kinetics of volume instability of the conducting polymer gels depend on the kind of solvent, composition and even size of the gel film. The mechanism of this dependency has been discussed. This size-dependent inetics of the conducting polymer gel indicates that the integration of small gel films and fibers should be effective to realize the acrtuators having repid responsibility.A bimorph film composed of poly(3-alkylthiophene) gel and polypyrrole films has been prepared and its characteristics have been studied. This bimorph film bends upon changes in temperature, solvent, chamical and electrochemical doping. The conditions were optimized to improve the characteristics of gel actuator. The transient characteristics of the bimorph film have been studied and an anormalous transient phenomemon ws obseved. Novel functional gel application was proporsed utilizing this anormaly.These results allow us to conclude important gide line for practical applications of the conjugated conducting polymer gels.
