dc.description.abstractThin films of methylcellulose doped adipic acid (MCAA) made it a good mechanical property. The films were prepared by solution-cast technique. Methylcellulose, a white powder, was added into acetic acid to form methylcellulose acetate and stirred. Until the mixture reached homogenous state, it was added with adipic acid with different concentration and continued to be stirred thoroughly until it become homogenous. Then the mixture was casted into Petri dishes and let dry. Then, transparent and prismatic clear thin films of MCAA were formed. The samples were kept in plastic bags and labelled or further characterizations. Instrument and methods used was Electrochemical Impedance Spectroscopy (EIS). Cole-Cole plots showed that the conductivity, u is proportional to the salt concentration and also to the temperature. The highest conductivity for the sample at room temperature is 4.66 X 10-9 5 m-1 . With temperature applied, the highest conductivity, u that obtained is 5.59 x 10-95 m-1at temperature of 373 K. The potential energy curve plotted indicated that the MCAA thin films are a good conducting material that there is getting less energy barrier needed for the chemical reaction, at higher temperature for physical transport in forming products. In the study of dielectric and electrical study, all the dielectric constants and modulus showed increment together with the increased of frequencies, as the salt concentration increases. This indicated that the higher values of concentration give rise to inter-particle hindrance and dipolar motion giving rise to higher values of dielectric constant as investigated by Yadav and Gandhi (1992).en_US
