摘要

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.
