Electrospinning of polyacrylonitrile nanofibers

Abstract: Polyacrylonitrile (PAN) was electrospun in dimethylformamide as a function of electric field, solution flow rate, and polymer concentration (C). The fiber diameter increased with C and ranged from 30 nm to 3.0 mm. The fiber diameter increased with the flow rate and decreased when the electric field was increased by a change in the working distance; however, it did not change significantly when the electric field was varied by a change in the voltage at a given working distance. The fibers below about 350 nm di… Show more

“…In addition, electrospinning PAN has been well researched and optimized. 22,23 The literature in this field is focused on the use of PAN as a carbon fiber precursor. 21,24 Although the chemical and physical property transition during carbonization is well-known, 25 the effect of carbonization on transport properties of electrospun materials remains undetermined.…”

“…However, PAN-10, PAN-15 and PAN-20 nanobers have a broader ber diameter distribution and comparatively high diameter range from 120 to 650 nm. We assume that the increased viscosity due to the higher crown ether fractions 33 and the reduced solution conductivity are the primary reason of ber thickening. Fig.…”

“…Uniaxially aligned fiber films were fabricated by electrospinning poly(acrylonitrile-comethylacrylate, random copolymer, 4 mole percent of methylacrylate) (PAN-MA) on a highspeed rotating metal drum [10]. Briefly, an 18% PAN-MA (w/v) solution was prepared by dissolving PAN-MA in the organic solvent, N, N,-Dimethyl Formamide (DMF, Acros) at 60°C…”
