采用含氧化钌（RuO2）的非活化多壁碳纳米管(MWCNT) -离子液体（IL）凝胶电极制备了致动器，并将其电化学和机电性能与单壁碳纳米管（SWCNT）致动器进行了比较。含ruo2的非活化MWCNT电极的双层电容比仅含MWCNT电极的双层电容大。在应变和最大产生应力方面，含有ruo2的非活化MWCNT聚合物致动器的性能优于纯MWCNT和纯swcnts致动器。MWCNTs和ruo2都需要生产大应变和快速响应的致动器，这些致动器的性能要超过单swcnts聚合物致动器，并具有足够的实际应用特性（例如触觉显示）。
The electrochemical and electromechanical properties of actuators developed using a non-activated multi-walled carbon nanotube (MWCNT)–ionic liquid (IL) gel electrode containing ruthenium oxide (RuO2) were compared with only-MWCNT and only-single-walled carbon nanotube (SWCNT) based actuators. The double-layer capacitance of the non-activated MWCNT electrode containing RuO2was larger than that of the only-MWCNT electrode. The non-activated MWCNT polymer actuator containing RuO2surpassed the performance of the only-MWCNT and only-SWCNT actuators in terms of the strain and maximum generated stress. Both MWCNTs and RuO2were required to produce large strain and quick response actuators that surpassed the performance of the only-SWCNT polymer actuator and exhibited characteristics sufficient for practical applications (e.g. tactile display).
