Preparation and Characterization of Solid Polymer Electrolyte Based on Epoxidized Jackfruit Gum
Main Article Content
Abstract
An attempt to prepare a solid polymer electrolyte from jackfruit gum was made. Jackfruit gum (JG) was purified and subjected to epoxidation process. Lithium perchlorate (LiClO₄) was dispersed in JG and epoxidized jackfruit gum (EJG). The structural characterizations were made through NMR spectroscopy and gel permeation chromatography. Ion conductivity and melting point of JG/LiClO₄ and EJG/LiClO₄ were measured. Obtained results indicated that epoxy group was introduced in JG and chain scission did not occur during the epoxidation. Ion conductivity of EJG/LiClO₄ in epoxidized natural rubber matrix was about 100 times higher than that of JG/LiClO₄ in epoxidized natural rubber matrix. EJG and LiClO₄ formed a liquid crystal. These may suggest the strong interaction between epoxy groups in EJG and LiClO₄.
