离子空间可达性决定碳纳米管电化学肌肉的有效驱动
Ion Accessibility Governs Electrochemically Effective Actuation in Carbon Nanotube Muscles
AI 导读
研究以 EMIm·BF4 溶于 PC、TMP 及其混合溶剂构建溶剂可调平台，在保持相同离子种类和 CNT 结构下发现，2.5 V 时收缩率从 PC 中的 50.4% 降至 TMP 中的 2.1%，降幅超过 20 倍，而电荷存储的下降远小于此。
推荐理由
研究用同一离子种类、同一 CNT 结构只换溶剂，把电荷存储与机械输出分开，读者可据此理解离子可达性对电化学驱动的影响。
创新点
在固定离子种类与 CNT 结构的条件下仅改变溶剂，把空间离子可达性从电荷存储中分离出来，作为电化学–机械耦合的控制因素。
