We prepared PEO nano fiber with different concentration of PEO acid solution by electrostatic spinning in different technology conditions. Then we studied the property of solution by rotary viscometer instrument and electrical conductivity spectrometer, the disperse form of the fiber by SEM scattered forms, the thermal property of the composite was studied by thermogravimetry and derivative thermogravimetry (TG-DTA). The conclusion is the disperse form of fiber is controlled by the concentration of solution, the voltage of spinning, the distance of solidification. The important factor is about the solution. To increase the solution viscosity and the solidification distance, reduce the spinning voltage would decrease the diameter of the fiber. Thermal stability of fiber was significantly better than powder.

In the current studies, polyaniline (PANi) was prepared both chemical and electrochemically in the presence of different bronsted acids from aqueous solutions. The effect of thermal treatment on electrical conductivity, and thermal stability of the PANi conducting polymers were investigated using 4-point probe and TGA techniques respectively. It was found that polymer prepared by CV method is more thermally stable than those prepared by the other electrochemical techniques. In this paper we have also reviewed some fundamental information about synthesis, general properties, diverse applications, thermal and environmental stability of polyaniline conducting polymers.
