A simple and facile approach to fabricate PVP fibers by wheel-spinning technique was investigated. Poly(vinyl pyrrolidone) sol (PVP, Mw =1,300,000, 6-14 w% in ethanol) was used as the candidate polymeric material. It was demonstrated by a rotating wheel with the speeds of 18.84, 15.70 and 12.56 m/s, respectively, PVP fibers can be drawn with diameters ranging from under 200 to over 2 μm and controlled by changing the rotating speed and sol concentration. The morphologies of the wheel-spinning… CONTINUE READING
