摘要

摘要: 将一种全氟磺酸树脂(Nafion)与多壁碳纳米管(MWCNTs)分别按质量比100:1、 100:3、 100:5进行配比, 采用溶剂浇铸法配合超声波分散法制备MWCNTs/Nafion型离子交换膜(IEM), 在此基础上利用化学沉积法制备铂型离子聚合物金属复合材料(Pt-IPMC), 考察三种MWCNTs负载量对IEM及Pt-IPMC性能的影响。采用SEM配合EDAX研究Pt的沉积效果, 对IEM及Pt-IPMC试样进行拉伸测试, 采用数字信号发生器为激励源测试Pt-IPMC的动态位移。结果表明: 添加MWCNTs使Pt-IPMC的内、外电极厚度分别增加200%~250%和180%~200%, 使IEM及Pt-IPMC的弹性模量分别提高57.92%~140.85%和9.06%~52.85%; MWCNTs有效修饰了Pt-IPMC的内电极, 并明显提升其动态位移量、动态响应及变形速度。

Abstract: A kind of multi-walled carbon nanotubes (MWCNTs)/perfluorosulfonate resin (Nafion) ionic exchange membrane(IEM) was prepared with Nafion solution and MWCNTs by mass ratios of 100:1, 100:3 and 100:5 using solvent evaporation method and ultrasonic dispersion method. Based on the IEMs, Ionic exchange polymer metal composites with Pt as electrodes (Pt-IPMC) were manufactured by chemical deposit method. The influence of MWCNTs contents on IEM and Pt-IPMC performance was investigated. The effect of Pt deposit was measured with SEM and EDAX, mechanical properties of IEM and Pt-IPMC samples were studied by tension testing, and Pt-IPMC dynamic deformation was observed under different excitation signals. The experimental results reveal that, owing to the MWCNTs, thicknesses of inter-locked electrodes and surface electrodes are respectively increased by 200%~250% and 180%~200%, elastic moduli of IEM and Pt-IPMC are respectively increased by 57.92%~140.85% and 9.06%~52.85%, inter-locked electrodes of Pt-IPMC are effectively modified. The samples’ dynamic displacement, response and deforming velocity are enhanced.
