Abstract This paper describes the effect of the addition of fumed silica nanoparticles in a composite gel electrolyte based on cellulose acetate and LiClO 4 . Changes in the viscosity, conductivity, morphology, diffusion and dynamic process of ion transport to a conductive polymer film on an ITO substrate were characterized to determine the nature of the nanoparticle interaction with the gel electrolyte. Fumed silica nanoparticles and cellulose acetate formed a linked network resulting in a highly viscous gel. The resulting composite gel electrolyte had a viscosity of 982.1 mPa·s and a conductivity of 4.39 ± 0.30 mS cm −1 at 25 °C, with potential applications including in electrochemical devices.

基于醋酸纤维素和纳米颗粒的高粘性复合凝胶电解质

摘要 本文描述了在基于醋酸纤维素和LiClO 4 的复合凝胶电解质中添加气相二氧化硅纳米粒子的效果。对离子传输到 ITO 基板上的导电聚合物膜的粘度、电导率、形态、扩散和动态过程的变化进行表征，以确定纳米颗粒与凝胶电解质相互作用的性质。气相二氧化硅纳米粒子和醋酸纤维素形成连接网络，产生高粘性凝胶。所得复合凝胶电解质在 25°C 下具有 982.1 mPa·s 的粘度和 4.39 ± 0.30 mS cm -1 的电导率，具有包括电化学装置在内的潜在应用。
