Compliant electrodes (CEs) were prepared from deproteinized natural rubber (DPNR) and multi-walled carbon nanotubes (MWCNTs) using Triton X-100 as a dispersing agent. Dielectric elastomers (DEs) were fabricated, from the DPNR incorporated with functionalized MWCNTs as a high dielectric constant filler, by film casting and the UV-curing process. The effect of MWCNT concentrations on mechanical and electrical properties of the CEs and DEs were individually examined. The defection responses and the dielectrophoresis forces of DEs and DEs attached on one side with CEs (DEs/CEs) were investigated as functions of electric field strength. The 5% v/v MWCNTs composite (CE_5) showed the highest conductivity of 19.7 S/cm and was subsequently used in the DEs/CEs bending experiment. The 2.5 phr of functionalized MWCNTs composite (DE_2.5) showed the highest dielectric constant of 15.4, but a relatively low bending actuation due to its initial high rigidity. The DE_1/CE_5 bilayer composite possessed the highest bending actuation, namely the largest bending distance and the dielectrophoresis force, presumably from the additional polarizations within CE_5 and the interactions with DE_5.

使用 Triton X-100 作为分散剂，由脱蛋白天然橡胶 (DPNR) 和多壁碳纳米管 (MWCNT) 制备顺从电极 (CE)。介电弹性体 (DE) 是由 DPNR 通过薄膜浇铸和 UV 固化工艺与功能化 MWCNT 作为高介电常数填料结合而成的。单独检查了 MWCNT 浓度对 CE 和 DE 的机械和电气性能的影响。作为电场强度的函数，研究了 DEs 和在一侧附着有 CE (DEs/CEs) 的 DEs 的缺陷响应和介电泳力。5% v/v MWCNTs 复合材料 (CE_5) 的最高电导率为 19.7 S/cm，随后用于 DEs/CEs 弯曲实验。2.5 份功能化 MWCNTs 复合材料 (DE_2. 5) 表现出最高的介电常数，为 15.4，但由于其初始的高刚性，其弯曲驱动相对较低。DE_1/CE_5 双层复合材料具有最高的弯曲驱动，即最大的弯曲距离和介电泳力，可能来自 CE_5 内的附加极化和与 DE_5 的相互作用。
