Investigation of Thermal and Electrical Conductivity Properties of Carbon Black Coated Cotton Fabrics

Öz In this study, the thermal and electrical conductivity properties of carbon black coated cotton fabrics were investigated. To obtain coated cotton fabrics, first carbon black nanoparticles were dispersed in distilled water. To improve dispersion stability of water based carbon black coating solutions, anionic wetting and dispersing agent was used. Plain weaved cotton fabrics were dipped into carbon black dispersion for 5 min. Because of the strong absorption, the cotton fabric was quickly coated by the carbon black dispersion. Then, the fabric with carbon black dispersion was subsequently dried in an oven at 120 °C for 10 min to remove water. The dipping-drying process was repeated for 5 times to increase the carbon black loading in cotton fabric. Different carbon black concentrations on coating process were examined. The effect of carbon black loading on thermal and electrical conductivity properties of fabrics were investigated.
