Figure 7From: Tailoring the grooved texture of electrospun polystyrene nanofibers by controlling the solvent system and relative humidityElectrospun fibers and formation mechanism. (A, B, C) Representative images of fibers electrospun from 10% (w/v) PS solution (THF/DMF ratio 4:1 v/v). RH 60%, collecting distance 15 cm, feeding rate 1.5 ml/h, and applied voltage 12 kV. (D) Formation mechanism of single grooved texture.Back to article page
