可拉伸復合單層電極用于低壓電介質執(zhí)行器——結論、致謝！

4.結論
首次將Langmuir-Schaefer方法用于DEAs電極的制備。將多壁碳納米管和聚（烷基噻吩）結合在一起，在空氣-水界面形成穩(wěn)定的單分子膜，然后使用Langmuir-Schaefer技術將其轉移到PDMS膜上。單層電極由嵌入鉑單層中的互連多壁碳納米管網(wǎng)絡組成，其中鉑賦予機械性能，而多壁碳納米管確保系統(tǒng)的導電性。復合單分子膜可拉伸，導電率高達100%(～20 MΩ/0%應變時，～5 GΩ/在100%應變下）。使用LS方法制作圖案化超薄可拉伸電極，可以制作具有1.4μm厚PDMS介電膜的薄DEA。僅在100V下，該DEA達到4.0%線性應變。與DEAs通常需要的kV驅動電壓相比，這種低工作電壓為DEAs開辟了新的應用領域。我們在這里報告的LS電極是DEA在小于5V時產(chǎn)生全應變的關鍵構件：通過使用LS/LB技術制造彈性體和電極，將有可能制造多層DEA，其中所有層都是一個單分子厚度。這將是DEA技術的最終物理極限。
