| Abstract: |
| In this work, an actuate membrane and an electrode membrane were prepared by a sol-gel method. And then, they were physically pressed to form a chitosan-based ion actuator (CSIA). Importantly, the effect of sodium chloride on CSIA was investigated.The mechanical properties of CSIA were tested by establishing an output force test platform and a displacement test platform while testing its porosity. And, the electrochemical performance was tested by electrochemical workstation. At the end, the surface morphology and functional groups were measured by scanning electron microscopy and infrared spectrogram, respectively. The results indicated that the molar concentration of the sodium chloride was the best at 0.06836 mol·L-1 for CSIA. Its mechanical properties could reach an output force of 2.939 mN and a deflection displacement of 4.025 mm, and the maximum porosity of 12.98 % at the same time. The specific capacitance of the electrochemical performance was up to 0.07719 F·g-1, and the minimum resistance reached 13.48 Ω. From the surface morphology and functional groups, the appropriate doping ratio of NaCl into CSIA was helpful for increasing the transport space of internal ions. The effective internal ion concentration and significantly reduced internal stress provided excellent performances under the appropriate voltage conditions. The doping of inorganic ion sodium chloride improved the internal electron transport efficiency of chitosan ion actuator, and it advanced the mechanical properties of the actuator. Hence the enhancement of NaCl output force in CSIA had a good significance for the development of inorganic salt ion strengthened ion actuator. |

| 氯化钠对提高壳聚糖基离子致动器性能的影响 崔朝阳1, 赵晓丽2, 贾炜坤2, 任月明1,徐岩2, 吕艳卓1 1.哈尔滨工程大学，材料科学与化学工程学院;2. 哈尔滨工程大学，机电工程学院 摘要：本研究采用溶胶-凝胶法制备了致动器膜和电极膜。然后，通过物理压制形成了壳聚糖基离子致动器（CSIA）。重要的是，通过建立输出力测试平台和位移测试平台测试 CSIA 的力学性能及其孔隙率，研究了氯化钠对 CSIA 的影响。此外，通过电化学工作站测试了电化学性能。最后，分别用扫描电子显微镜和红外光谱图测量了表面形貌和官能团。结果表明，氯化钠浓度为 0.06836 mol. L-1 时 是CSIA 的性能最佳。其最大输出力可达 2.939 mN ，最大挠曲位移有 4.025 mm，最大孔隙率为 12.98 %。电化学性能的比电容高达 0.07719 F g-1，最小电阻达到 13.48 Ω。从表面形貌和官能团来看，CSIA 中适当的 Nacl 掺杂比例有助于增加内部离子的传输空间。在适当的电压条件下，有效的内部离子浓度和显著降低的内部应力提供了优异的性能。无机离子氯化钠的掺杂提高了壳聚糖离子致动器的内部电子传输效率，并改善了致动器的机械性能。因此，CSIA 中 Nacl 输出力的增强对无机盐离子强化离子致动器的开发具有重要意义。 关键词：氯化钠；壳聚糖；掺杂；离子致动器 |
