A series of poly(ethylene oxide)-LiOTf electrolyte films were prepared using a variety of hydrocarbon templates as nanofillers, resulting in observable nanophase separation in the polymer electrolyte. Upon partial extraction of the nanofiller template, an enhanced conductivity over 2 orders of magnitude was measured using ac impedance. Scanning electron microscopy, differential scanning calorimetry, and thermogravimetric analysis were employed to characterize the porosity, composition, and mass loss of template-extracted and nonextracted film samples.
使用多种烃类模板作为纳米填料制备了一系列聚环氧乙烷-LiOTf电解质膜,导致聚合物电解质中出现明显的纳米相分离。在部分提取纳米填料模板后,使用交流阻抗测量得到电导率提高了2个数量级以上。采用扫描电子显微镜、差示扫描量热法和热重分析法对模板提取和未提取的薄膜样品的孔隙率、组成和质量损失进行了表征。
