纳米碳/金属复合界面电极的可控制备及其对IPMC力电特性的强化机制研究

离子聚合物-金属复合材料(Ionic Polymer-Metal Composite, IPMC)是一种新兴的智能驱动材料，在微纳驱动等领域极具应用前景。然而，现有IPMC的力电特性及其一致性尚未达到实际应用需求的水平，虽已有研究证实纳米碳/金属复合界面电极对IPMC力电特性具有增强作用，但对其形成机制和功能机制缺乏系统研究和认识，这严重制约着IPMC的进一步发展。本项目提出开发厚度及形貌可控的纳米碳/金属复合界面电极，并揭示其对IPMC力电特性的强化机制。通过对纳米碳/金属复合界面电极的形貌特征及关键影响因素进行研究，阐明其形成机制，实现其厚度及形貌可控制备；提出复合界面电极结构表征方法，揭示其结构特征、物理参数及材料力电特性之间的相互作用关系；明确复合界面电极结构参数对IPMC力电特性的功能机制和影响水平，形成面向应用需求的界面电极结构参数调控策略，为推进IPMC工程化奠定基础。

As a new kind of bionic actuating material, Ionic Polymer-Metal Composite (IPMC) exhibits several unique characteristics, such as flexibility, low driving voltage and large deformation etc., with a wide range of applications in bionic and intelligent actuating areas. However, the electromechanical properties and consistency of current IPMCs cannot meet the requirements of practical applications. IPMC with nano-carbon/metal composite electrodes has excellent interface structure and characteristics between electrode and inner membrane, thereby exhibiting excellent electromechanical properties. However, there is still lacking in systematic investigating and understanding in its preparation.technology, influencing factors and functional mechanisms, which seriously restricts further development of IPMCs. Therefore, to solve this problem, this project proposes a novel preparation technology in preparing IPMCs with nano-carbon/metal composite electrodes with controllable thickness and morphology. Through studying the formation process and morphology of the nano-carbon/metal composite interface electrodes and their key influencing factors, it proposes to reveal the formation mechanism and control strategy of the nano-carbon/metal composite interface electrodes, and further to reveal the interaction between interface morphology, physical parameters and electromechanical behaviors of the IPMCs. Furthermore, it proposes to reveal the functional mechanism and influencing level of the composite interface electrode structure parameters on the electromechanical properties of the IPMCs. On this basis, it proposes to explore the actual requirement-oriented regulation methods of the interface properties. Obviously, the research results will effectively improve the electromechanical properties and consistency of IPMCs, and then promote their development and practical applications.
