In-situ annealing and characterization of superhydrophobic electrospun poly(acrylonitrile) ionized nanofibre smart material properties

Abstract

Poly(acrylonitrile) (PAN) electrospun nanofibres were stabilized at 285°C in surrounded conditions for 1 h and then carbonized at 900°C for 1 h in inert nitrogen (N) at 10 psi. The resulting carbonized PAN nanofibre films were fabricated into square pieces and exposed to several classification procedures. Raman spectroscopy analysis was used to stretch approximately 920 cm−1 of the designated construction of the G-band of the carbonized nanofibres. Energy-dispersive X-ray (EDX) spectroscopy was used to examine the chemical structures and elemental distribution of the carbonized PAN nanofibres. EDX spectroscopy revealed the PAN carbon core at roughly 61%. After annealing, the PAN carbon nanofibres were 89% carbon weight (atomic %), with N and minor quantities of Ni and O. The structure was confirmed by X-ray diffraction for bulk PAN and carbonized PAN nanofibres. Examination of the outcomes may be valuable for improving the use of various smart nanofibre materials in the industry and for water treatment sensor applications.
