摘要

基于固体聚合物电解质的能源装置在未来的能源中起着至关重要的作用。采用纳米CdS制备了固态聚环氧乙烷聚合物电解质。将前驱体Cd(NO3)2掺入宿主聚合物中形成薄膜，并将H2S气体暴露在薄膜上使其转化为Cd。宿主聚合物本身充当封盖剂，以减小CdS纳米颗粒的尺寸。利用透射电子显微镜(TEM)和原子力显微镜(AFM)研究了CdS颗粒在基体内部的尺寸分布和表面性能。利用傅里叶变换光谱(FTIR)对复合材料中的官能团进行了分析。采用阻抗分析仪对聚合物纳米复合电解质的电学特性进行了表征。从电学研究中观察到，通过改变CdS:PEO的比例，离子电导率增加。

Structural and electrical properties of CdS nanocomposite solid films for electrolyte applications

ABSTRACT Solid Polymer electrolyte-based energy devices are playing a vital role for future energy sources. Solid state Poly (ethylene Oxide) polymer electrolyte was prepared by incorporating CdS nanoparticles. The precursor Cd(NO3)2 was incorporated in the host polymer to form a film and H2S gas was exposed on the film to convert it into CdS. The host polymer itself acted as a capping agent to reduce the size of CdS nanoparticles. The size distribution of CdS particles inside the matrix and the surface property were studied using Transmission Electron Microscope (TEM) and Atomic force microscope (AFM). The functional group present in the composites had been analyzed using Fourier Transform spectroscopy (FTIR). The electrical characteristics of the polymer nano composite electrolyte were characterized using impedance analyzer. The increase in ionic conductivity by varying the ratio of CdS:PEO was observed from the electrical studies.

期刊介绍： Providing a common forum for all soft matter scientists, Soft Materials covers theory, simulation, and experimental research in this rapidly expanding and interdisciplinary field. As soft materials are often at the heart of modern technologies, soft matter science has implications and applications in many areas ranging from biology to engineering. Unlike many journals which focus primarily on individual classes of materials or particular applications, Soft Materials draw on all physical, chemical, materials science, and biological aspects of soft matter. Featured topics include polymers, biomacromolecules, colloids, membranes, Langmuir-Blodgett films, liquid crystals, granular matter, soft interfaces, complex fluids, surfactants, gels, nanomaterials, self-organization, supramolecular science, molecular recognition, soft glasses, amphiphiles, foams, and active matter. Truly international in scope, Soft Materials contains original research, invited reviews, in-depth technical tutorials, and book reviews.
