Investigation of Chloro Pentaammine Cobalt(III) Chloride- Polyvinyl Alcohol Composites

Conductive polymer composites have been widely used in industrial applications, such as biomedical devices , self-heating materials, electrostatic dissipation and over current protectors. This paper investigate the study of the effects of Chloro Pentaammine Cobalt(III) Chloride complexes on Electrical properties of polyvinyl alcohol. samples were prepared using casting technique. The experimental Results show that the electrical conductivity of polyvinyl alcohol is increased with increasing the weight percentages of Chloro Pentaammine Cobalt(III) Chloride complexes and temperature. The activation energy of D.C electrical conductivity is decreased with increase of Chloro Pentaammine Cobalt(III) Chloride complexes concentration. keywords: polyvinyl alcohol, conductivity, activation energy , Composites
