IPMC的制备及其电极结构的表征

Preparation of lonomer/Metal Composites (IPMC)and Characterization of the Electrode

由聚乙烯-乙烯醇(EVOH)和1,3-丙烷磺酸内酯合成了EVOH磺酸钾离子聚合物(EVOH-SO_3K),并用2,4-甲苯二异氰酸酯(TDI)对其进行了交联改性,得到TDI改性EVOH磺酸钾离子聚合物(EVOH-TSO_3K),通过EVOH-TSO_3K溶液的铸膜和化学沉积制得离子聚合物膜金属复合材料(IPMC)。采用傅立叶变换红外光谱(FT-IR)、扫描电子显微镜(SEM)分别对EVOH-TSO_3K及其IPMC进行了结构表征。结果表明,EVOH-TSO_3K形成了交联结构,银金属电极均匀沉积在聚合物膜表面。通过三次化学沉积,IPMC表面电阻可达到8×10^(-1)Ω/mm^2,从而在外加负载电压下(3V)实现了电形变,电形变角度达到36°。

Poly（ ethylene eovinyl alcohol） end - capped with potassium sulfonate （ EVOH - SO3 K） was synthesized by sulfonification of poly（ ethylene covinyl alcohol） （EVOH） with 1,3 -propane suhone and was modified by toluene -2,4 -diisocyanate （TDI） to get a cross- linked ionic polymer （EVOH -TSO3 K）, and then the IPMC based on EVOH -TSO3 K was prepared through the method of chemical deposition. The ionomer and its IPMC were characterized by FT - IR and SEM, respectively. The experimental results indicated that EVOH - TSO3 K had been obtained. The electrode based on argentum was deposited uniformly on the surface of ionomer, IPMC with the surface resistance of 0.8Ω·mm^-2 could be deformed under 3V applied voltage through three times chemical deposition, and the deformation angle could reach 36°.
