4.結(jié)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(jié)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(shù)將其轉(zhuǎn)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(luò)組成，其中鉑賦予機(jī)械性能，而多壁碳納米管確保系統(tǒng)的導(dǎo)電性。復(fù)合單分子膜可拉伸，導(dǎo)電率高達(dá)100%(～20 MΩ/0%應(yīng)變時(shí)，～5 GΩ/在100%應(yīng)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(dá)到4.0%線性應(yīng)變。與DEAs通常需要的kV驅(qū)動(dòng)電壓相比，這種低工作電壓為DEAs開辟了新的應(yīng)用領(lǐng)域。我們在這里報(bào)告的LS電極是DEA在小于5V時(shí)產(chǎn)生全應(yīng)變的關(guān)鍵構(gòu)件：通過使用LS/LB技術(shù)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(gè)單分子厚度。這將是DEA技術(shù)的最終物理極限。
