中文摘要：

适于工程中对大动力人工肌肉（IPMC）应用的需要，探索厚层IPMC的制备。首先利用凝胶法制出IPMC原膜，然后以Nafion液为粘剂并通过对多片原膜进行热粘压处理，制成多层式基体膜，再经膜表面粗化、离子交换和化学沉积等工艺制成多层IPMC。利用电镜观察到多层IPMC层间接合致密性。进行了双层IPMC性能实验，结果显示，双层IPMC在保证弯曲变形基本不下降的前提下，动力提高到单层的1．8倍，表明用热粘压法制备IPMC可部分解决其动力小问题。

英文摘要：

To meet the demands of ionic polymer-metal composite applied in practical engineering, the prepara- tion of the multi-layer IPMC has been studied. Firstly, based on the sol-gel method, how to make use of Du Pont Nafion-liquid to prepare the primary nafion-membrance is proposed. Then, by utilizing Nafion liquid as ad- hesives, multiple membranes are combined into a multilayer film with the heat pressure method. And finally, the multi-layer IPMC is processed with techniques of surface coarsening, ion exchange and electroless-plating. The reliable densification of inner structure of multi-layer IPMC is found in section analyses with SEM. Tile c lectro-mechanical properties of multi-layer IPMC are tested. The results show that： comparing with single layer IPMC, the dual-layer IPMC is capable of increasing output power by 80% without significant reduction of ben ding displacement, which suggests that to some extent, the proposed technique is a better solution to the prob lems of IPMC＇s insufficient output power.
