  • Ohmic joule heating electrodes were developed for the electrical heater of the floor of a room. A composite slurry of super pure black and polyvinylidene fluoride with/without the additives of multi-walled carbon nanotube or kindney stone powder was coated as a thin film on the polyethylene terephthalate film. The performances of heating electrodes were evaluated checking specific conductivity, adhesion strength and hardness. The addition of kindney stone powder increases specific resistance and hardness in a small extent. However, the addition of carbon nanotube increases specific conductivity and hardness. The properties of various compositions of ohmic joule heating electrodes were evaluated.
