Abstract

In this study, we propose to neutralize the relaxation deformation of Nafion-ionic polymer metal composite (IPMC) by slow anode deformation of Flemion-IPMC caused by carboxyl groups (-COOH). Carboxylated carbon nanotubes (CCNT) as -COOH carriers were doped into a Nafion matrix. By adjusting the doping content from 0 wt% to 10 wt%, an IPMC with constant steady-state deformation has been achieved at a critical CCNT content of 2 wt%. Moreover, the increasing rate of the slow anode deformation with the CCNT content is tunable, which is found to be 2.26 mm s %.

摘要

在本研究中，我们提议通过羧基（-COOH）引起的 Flemion 离子聚合物金属复合材料（IPMC）的缓慢阳极变形来抵消 Nafion 离子聚合物金属复合材料（IPMC）的松弛变形。将羧化碳纳米管（CCNT）作为 -COOH 载体掺杂到 Nafion 基体中。通过将掺杂含量从 0 wt% 调整到 10 wt%，在 2 wt% 的临界 CCNT 含量下实现了具有恒定稳态变形的 IPMC。此外，缓慢阳极变形随 CCNT 含量的增加速率是可调的，发现其为 2.26 毫米/秒。
