本文介绍了一种瓣阀式离子聚合物金属复合材料（IPMC）微泵的设计、制造和实验特性，其膜片由柔性材料支撑。基于Nafion/层状硅酸盐和Nafion/二氧化硅纳米复合材料的多层IPMC被制造并用作微泵的致动器。为了充分利用柔性IPMC隔膜，我们引入了柔性支撑的概念，并通过在其周边支撑具有顺应性聚二甲基硅氧烷（PDMS）结构的IPMC致动器来实现该概念。然后，我们制作了一个IPMC微型泵与IPMC隔膜和瓣阀由PDMS材料制成。实验和有限元分析进行证明的概念，灵活的支持和表征的多层IPMC膜片和IPMC微泵。在3V的施加电压和3 Hz的驱动频率下记录到760 μ l/min的最大流速和1.5kPa的最大背压，即使性能持续了几分钟。所提出的微型泵是有吸引力的，由于其低的工作电压，没有泄漏问题，简单的设计，易于制造。(C)2007 Elsevier B.

This paper presents the design, fabrication and experimental characterization of a flap valve ionic polymer metal composite (IPMC) micropump, the diaphragm of which is supported by a flexible material. A multilayered IPMC based on a Nafion/layered silicate and Nafion/silica nanocomposites was fabricated and used as an actuator for the micropump. To make best use of a flexible IPMC diaphragm, we introduced a concept of flexible support and implemented the concept by supporting an IPMC actuator with a compliant polydimethylsiloxane (PDMS) structure at its perimeter. We then fabricated an IPMC micropump with the IPMC diaphragm and flap valves made from the PDMS material. Experiments and finite element analyses were performed to justify the concept of flexible support and to characterize the multilayered IPMC diaphragm and the IPMC micropump. A maximum flow rate of 760 mu l/min and a maximum backpressure of 1.5 kPa were recorded at an applied voltage of 3 V and a driving frequency of 3 Hz, even though the performance lasted for a few minutes. The proposed micropump is attractive due to its low operational voltage, lack of leakage problems, simple design, and ease of manufacturing. (C) 2007 Elsevier B.V. All rights reserved.
