Influence of Stripping Solution’s Concentration on the Seebeck Coefficient of Nickel-Coated Carbon Fibers

Sensors and actuators made out of textile materials are the subjects of many research activities, especially because of the specific properties possessed by the textiles. In this context, yarns with a different Seebeck coefficient can be applied for making a textilebased thermopile. Preliminary experiments have shown that a pair
of nickel-coated carbon fibers (NiCF) and carbon fibers (CF) has a good Seebeck coefficient. In this paper, we study the influence of the concentration of the solution used to strip off the Ni from the NiCF. Experiments show that a mixture of 37% HCl and 10% H2O2 (1:1) result in the highest Seebeck coefficient.
