Abstract Transparent and flexible functional materials are crucial to the development of modern electro-mechanical devices. In this work, the preparation process of the transparent ionic polymer-metal composite (IPMC) with Nafion/IL substrate and PEDOT:PSS electrodes was explored by combining solution casting method and roll coating method. Furthermore, the electro-mechanical characteristics and electro-active properties of so-made IPMCs were investigated. Orthogonal optimization was carried out to evaluate the influence level of key parameters, including substrate thickness, electrode roll coating content on each side, hot pressing time immersed in IL and the degree of roughness. The transparent IPMC prepared according to the orthogonal optimization parameters showed nice optical transparency, electrochemical and mechanical properties. The maximum peak-to-peak tip displacement of our transparent IPMC can reach 11.824 mm; in addition, the samples can activate under voltage with frequency up to 100 Hz. The research is of great significance to expand the fabrication method of IPMC and promote the application of this mate-rial in the field of transparent flexible electronic devices.
