Fabrication and characterization of carbon nanofibers from polyacrylonitrile/pitch blends

Fabrication and characterization of carbon nanofibers from polyacrylonitrile/pitch blends
Khalid Lafdi, Chang Liu
Continuous carbon nanofibers had been widely studied based on different processing methods and precursors. Especially, electrospinning was introduced as a versatile method for fabricating ultrathin fibers. However, as the limitation of precursor, pitch had not been well studied due to its viscosity and miscibility problem. A comprehensive study on the electrospinning of the blends [pitch and polyacrylonitrile (PAN)] was explored. Thermodynamic miscibility was studied by using differential scanning calorimeter. Fourier transfer infrared spectroscopy was used to show interaction and potential reaction between pitch and PAN molecules. Finally, smooth, continuous, and cylindrical carbon nanofibers were successfully fabricated by electrospinning technique. Based on Raman analysis result, the addition of pitch enhanced the carbon crystallite which improved the overall electrical conductivity and modulus of nanofibers. © 2017 Wiley Periodicals, Inc. J.
