本文提出了微针辊粗化（MNRR）作为离子聚合物-金属复合材料（IPMC）直接、方便、经济的粗化方法。在此基础上，我们调整了制备工艺的顺序，在第一次浸渍后对膜进行粗化，形成一个深针状的穿透电极，随后得到了在低频和高频下都有大变形的IPMC。结果表明，与传统工艺相比，该工艺的比电容和尖端位移分别可达到5倍和4倍。此外，还研究了载荷和轧制周期的影响，以确定最佳粗化水平。这种新的制造工艺提供了一种直接的方法，可以生产简洁而深入的界面，并可以进一步探索IPMC执行器的批量生产。
In this paper, microneedle roller roughening (MNRR) was proposed as a direct, convenient and cost-effective roughening method for an ionic polymer-metal composite (IPMC). On this basis, we regulated the sequence of the fabrication procedure, roughening the membrane after the first impregnation process to form a deep needle-like penetrated electrode, and subsequently obtained an IPMC with large deformation at both low and high frequencies. The results showed that the specific capacitance and tip displacement could reach five times and four times, respectively, compared with the results for fabrication using the traditional process sequence. In addition, the effects of the load and rolling cycles were also investigated to find the optimal roughening level. This new reported fabrication process provides a direct means of producing a concise and deep interface and may be further explored for batch production of IPMC actuators.
