DIFFUSIVITY AND ELECTRICAL PROPERTIES OF GUM ARABIC, CARBON BLACK/KBRO3 COMPOSITE MATERIAL
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 2015, Vol 4, Issue 4
Abstract
Porous Gum Arabic (GA) doped with carbon black (Soot) was prepared using solid state chemical method. Potassium spectroscopy (IS), scanning electron microscope (SEM) and Energy-dispersive X-ray Spectroscopy (EDS) were used in order to investigate the electrical properties of Gum Arabic, the diffusion coefficient, dielectric constant and the existence of elements, respectively. The results of diffusion coefficient and dielectric showed direct proportionality with the logarithmic frequency. The porosity of the sample was found to be directly proportional to the dielectric constant. The effect of temperature was profound as diffusivity and conductivity were found to increase with temperature.
