Abstract:

Electro-spinning is widely accepted as a simple and versatile technique for producing micro- and nano-structures. Using this method, micro-nano structured polystyrene(PS) was prepaired by controlling the concentration of PS/DMF solution. At 5%(mass fraction) PS/DMF solution with PS molecular weight of 250000, the surface shows super-hydrophobicity with water contact angle of about 167° and ultra-low adhesive force to water. Furthermore, molecular weight is also important to the surface morphology of the PS film formed by electro-spinning.

Key words: Electro-spinning; Surface adhesive force; Super-hydrophobic; Polystyrene film
