研究了聚合物种类（聚偏氟乙烯）（PVdF）均聚物或聚偏氟乙烯-六氟丙烯共聚物（PVdF（HFP）共聚物）、聚合物的平均分子量以及PVdF（HFP）中HFP的含量对聚合物支撑的单壁碳纳米管（SWCNT）-离子液体（IL）凝胶电极驱动器电化学和机电性能的影响。对于含有1-乙基-3-甲基咪唑四氟硼酸盐（EMI[BF（4）]）的PVdF（Kynar 741或761）致动器，在0.01-0.005 Hz的频率范围内产生的应变为0.90-1.05%，是PVdF（HFP）（Kynar Flex 2801）致动器的两倍多。此外，它被认为是HFP含量应低（或零）的大产生的应变和大的最大应力为零。PVdF致动器的性能比PVdF（HFP）致动器好得多，并且具有快速响应，足以用于实际应用（例如，触觉显示器）。皇冠版权所有（C）2011由Elsevier B.

The effects of polymer species (poly(vinylidene fluoride)) (PVdF) homopolymer or poly(vinylidene fluoride-co-hexafluoropropylene) (PVdF(HFP) copolymer), average molecular weight of the polymer, and the HFP content in PVdF(HFP) on the electrochemical and electromechanical properties of actuators using polymer-supported single-walled carbon nanotube (SWCNT)-ionic liquid (IL) gel electrodes were investigated. For the PVdF (Kynar 741 or 761) actuator containing 1-ethyl-3-methylimidazolium tetrafluoroborate (EMI[BF(4)]), the generated strain was 0.90-1.05% for the frequency range of 0.01-0.005 Hz, which was over twice as large as that for the PVdF(HFP) (Kynar Flex 2801) actuator. Furthermore, it is considered that the HFP content should be low (or zero) for large generated strain and zero for large maximum stress. The PVdF actuator performs much better than the PVdF(HFP) actuator and has a quick response, sufficient for practical application (e.g., tactile displays).
