摘要
为了降低成本并改善材料性能,采用银替代铂制备IPMC电极。基于渗透还原工艺采用化学沉积方法制备了Pt基、Pt-Ag基和Ag基三种IPMC柔性驱动器试件。对试件的SEM和XRD分析结果表明本文提供的方法可以有效地将电极金属沉积在基膜中,且呈梯度分布;对样件的致动效果以及表面电阻特性测试结果表明Ag基IPMC驱动器具有最好的致动变形能力和最低的表面电阻。在相同尺寸与约束条件下,Ag基IPMC在1.5V时产生90°变形,Pt型与Pt-Ag型IPMC分别在3V和4V驱动电压下产生60°变形。
To reduce the cost and improve characteristics of Ion-exchange polymer metal composite （IPMC）, argentums is utilized to fabricate the surface electrodes instead of platinum. Three kinds of IPMC flexible actuator specimens, with Pt, Ag-Pt and Ag surface electrodes, were respectively fabricated by chemical deposition based on infiltration reduction process. The results of SEM and XRD analysis on the specimens show that electrode metal particles can be effective infiltrated and reduced inside the membrane using the proposed approach. And the metal particle is gradient distribution throughout IPMC. The results of the actuated-deformation capabilities and surface resistance tests on the specimens indicate that Ag based IMPC actuator has the best electro-active bending deformation capability, the lowest surface resistance. The maximum bending angles, obtained under the same dimension and constraints situations, are respectively about 90° for the Ag based IPMC （driving voltage 1.5V） and about 60° for the Pt based and the Pt-Ag based.IPMC （3V and 4V respectively）.
