Thermal Diffusivity and Electrical Conductivity Studies of Polyaniline Based Materials and Selected Ceramics

In this work, the photoflash and four-point probe techniques were respectively applied for thermal diffusivity and electrical conductivity measurement on polyaniline, polyaniline blends, polyaniline composite and ceramic at room temperature. In the photoflash technique, the signal was initially...
