Abstract:

The control of surface morphology of polyoxymethylene(POM) nanofibers electrospun from hexaf-luoroisopropanol was investigated by varying relative humidity, temperature, solution concentration, electrical voltage and collecting distance. It is found that environmental conditions are very important for surface pore formation. The pores are obvious only when the fibers are produced beyond a certain relative humidity and certain temperature. Solution concentration affects the pore size, while instrumental parameters do not have ob-vious influence on pore formation. Possible mechanism for pore formation was discussed.

Key words: Polyoxymethylene, Electrospin, Surface, Pore
