离子聚合物金属复合材料（IPMC）是一种电活性聚合物。由于其具有驱动电压低、变形大、柔性好、重量轻等特点，在众多智能材料中，它正成为最受欢迎的智能材料之一。在这项研究中，提出了一种新颖的Nafion（R）薄膜结构来提高IPMC的性能。制备了具有厚度梯度结构的IPMC样品，并对其性能进行了研究，以证实梯度结构的有效性。通过实验比较了交流和直流电压作用下的变形位移和阻挡力。结果表明，厚度梯度结构可以提高变形位移和阻挡力的性能。
An ionic polymer metal composite (IPMC) is a kind of electro-active polymer. Due to the properties of low driving voltage, large deformation, flexibility and lightness, it is becoming one of the more popular from a diversity of smart materials. In this study, a novel structure of Nafion (R) film is proposed to improve the performance of an IPMC. IPMC samples with a gradient structure in thickness are fabricated and their performance is investigated to confirm the validity of the gradient structure. The deformation displacement and the blocking force are compared under AC and DC voltage by experiments. The results indicate that the structure of gradient in thickness would improve the performance both in deformation displacement and blocking force.
