Abstract

The design, fabrication and characterization of the carbon nanotubes (CNT)-cotton textile composite-based flexible thermoelectric cells are presented in this research. The piece of cotton textile was used as substrate and the constituent of CNT-cotton textile composite as well. To form the nanocomposite the CNTs were embedded in the cotton substrate by rubbing-in technique. The fabricated cells were investigated for temperature dependent Seebeck coefficient, thermoelectric resistance and short-circuit current. On rising temperature from 301 to 348 K the rise in the Seebeck coefficient and short-circuit current was found 2.15 times and 14 times, respectively, while the resistance of the cell fell by 1.53 time. Thermoelectric cells may be applied for the temperature gradient measurement and also as a converter (low power) of heat to electric energy. The major benefits of the fabricated thermoelectric cell are the following: use of environmentally friendly natural textile substrate, low-cost of materials (thermoelectric) and fabrication technology. The cell can be used as resistive temperature sensor because of its quasi-linear resistance–temperature relationship. This cell works as a multifunctional device. Textile substrates in the CNT-cotton textile composite-based thermoelectric cells make them shockproof..
