Journal Textile Coloration and Finishing Year / Vol., Issue, Month 2021 / V.33,no.4,Dec Title Energy Harvesting System according to Moisture Absorption of Textile and Efficient Coating Method as a Carbon Black Authors Seungjin Choi, Juwon Chae, Sangoh Lee1, and Jaewoong Lee* Institution/Affiliations Yeungnam University Pages/Total page pp.280 ~ 287 / 8 Language Korean Abstract Generating electricity by using water in many energy harvesting system is due to their simplicity, sustainability and eco-friendliness. Evaporation-driven moist-electric generators (EMEGs) are an emergent technology and show great potential for harvesting clean energy. In this study, we report a transpiration driven electro kinetic power generator (TEPG) that utilize capillary flow of water in an asymmetrically wetted cotton fabric coated with carbon black. When water droplets encounter this textile EMEG, the water flows spontaneously under capillary action without requiring an external power supply. First carbon black sonicated and dispersed well in three different solvent system such as dimethylformamide (DMF), sodiumdedecylbenzenesulfonate (SDBS-anionic surfactant) and cetyltrimethylammoniumbromide (CTAB-cationic surfactant). A knitted cotton/PET fabric was coated with carbon black by conventional pad method. Cotton/PET fabrics were immersed and stuttered well in these three different systems and then transferred to an autoclave at 120 oC for 15 minutes. Cotton/PET fabric treated with carbon black dispersed in DMF solvent generated maximum current up to 5 μA on a small piece of sample (2 μL/min of water can induce constant electric output for more than 286 hours). This study is high value for designing of electric generator to harvest clean energy constantly.
