Preparation of methyl grafted natural rubber and its application in super capacitor electrolytes
Due to continuous progress in science and technology and the pressure to seek low cost, green materials for electrochemical devices have led to discover the possibility to use natural rubber (NR) as a polymer for electrolytes. This study reports about modifying Sri Lankan NR and using it for a solid polymer electrolyte in fabricating super capacitors with natural graphite electrodes. Solid polymer electrolyte was prepared using methyl grafted NR as the polymer and magnesiumtrifluoromethanesulfonate as the salt. The composition, 1 NR: 0.80 magnesiumtrifluoromethanesulfonate showed the maximum room temperature conductivity of 3.36 × 10–3 Scm−1. Capacitive features were dominant at low frequencies. Initial single electrode specific capacitance was about 32 Fg−1 whereas the initial single electrode specific discharge capacitance was about 12.8 Fg−1. Even though the values are not very high, they are highlighting the suitability to launch further studies to enhance performance of super capacitors with NR based electrolytes.
期刊介绍：
The Journal of Rubber Research is devoted to both natural and synthetic rubbers, as well as to related disciplines. The scope of the journal encompasses all aspects of rubber from the core disciplines of biology, physics and chemistry, as well as economics. As a specialised field, rubber science includes within its niche a vast potential of innovative and value-added research areas yet to be explored. This peer reviewed publication focuses on the results of active experimental research and authoritative reviews on all aspects of rubber science.
The Journal of Rubber Research welcomes research on:
the upstream, including crop management, crop improvement and protection, and biotechnology;
the midstream, including processing and effluent management;
the downstream, including rubber engineering and product design, advanced rubber technology, latex science and technology, and chemistry and materials exploratory;
economics, including the economics of rubber production, consumption, and market analysis.
The Journal of Rubber Research serves to build a collective knowledge base while communicating information and validating the quality of research within the discipline, and bringing together work from experts in rubber science and related disciplines.
Scientists in both academia and industry involved in researching and working with all aspects of rubber will find this journal to be both source of information and a gateway for their own publications.
