The study of thermoelectric energy and mechanical properties by modifying carbon fiber fabric

Abstract

With the acceleration of global industrialisation, the scarcity and depletion of the world’s energy resources has become a problem that no country can ignore. It is a serious obstacle to the long-term stable development of society. Exploring and developing new energy sources has become the trend of global energy development. In this paper, hydrogen peroxide is used to treat carbon fibre materials. In addition, the thermoelectric reinforcing agent Bi2Te3 is doped into carbon fibre film materials by electrochemical deposition for the purpose of measuring the Seebeck coefficient and electrical conductivity. Technical abbreviations will be explained at the first use. By investigating how changes in the surface structure of carbon fibre fabrics and the addition of bismuth telluride affect their thermoelectric properties, this study establishes a framework for improving the thermoelectric capabilities of carbon fibre fabrics. Experimental results show that carbon fiber fabric treated with H2O2 have excellent thermoelectric and mechanical properties.
