通过氧化偶联聚合方法成功地制备出一种基于烷氧磺酸盐功能化的聚乙撑二氧噻吩水凝胶,揭示了零维单体胶束向二维纳米片层及三维水凝胶的转变过程,发现通过改变反应温度或初始单体浓度,可以诱导水凝胶网络结构单元的维度变化,即由零维纳米粒子向二维纳米片层进行转化.提出了一种导电高分子水凝胶的合成方法,即采用一种氧化剂与一种多价金属盐的混合物作为引发剂,其中前者用于诱导单体聚合,后者则充当离子交联试剂,并发现可以通过引入不同金属离子来改变凝胶的形貌.此外,导电高分子水凝胶具有良好的电化学电容,并具有选择性吸附与可控脱附某些染料分子的特性.
A polyoxyethylene dioxythiophene hydrogel functionalized with alkoxysulfonate was successfully prepared by oxidative coupling polymerization. The results showed that the zero-dimensional monomeric micelles migrated to two-dimensional nanosheets and three-dimensional hydrogel It was found that by changing the reaction temperature or the initial monomer concentration, the dimensional changes of the network structure unit of the hydrogel can be induced, that is, the transformation from the zero-dimensional nano-particles to the two-dimensional nano-plate layer is proposed. A conductive polymer water Gel synthesis using a mixture of an oxidizing agent and a polyvalent metal salt as an initiator wherein the former is used to induce the polymerization of monomers while the latter acts as an ionic crosslinking agent and it is found that the former can be obtained by introducing different metal ions To change the morphology of the gel.In addition, the conductive polymer hydrogel has good electrochemical capacitance and has the characteristics of selective adsorption and controlled desorption of certain dye molecules.
