MS received 22 October 2019; accepted 15 March 2020 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. Energydispersive 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. Keywords.

Introduction
Poly(acrylonitrile) (PAN) is generally the existing precursor in the large-scale production of effective carbon nanofibres [1,2]. Carbon nanofibres have been receiving significant attention because of their outstanding properties, including high mechanical strength and the Young moduli, high electrical and thermal conductivity, good resistance in terms of corrosion, fatigue and strength, high resistance of creep and superior stiffness. As a result, carbon nanofibres are being used extensively in applications involving heat treatment, extreme temperature catalysts, sensors, membrane based-filtration or absorption, photonics and nanoelectronics [3]. This study aimed to use the electrospinning technique with added PAN carbon nanofibres and heat treatment to eliminate non-carbonaceous material and to use them as sensors for various industrial applications. The main application of carbon nanofibre has been its synthesis for electrospinning, where PAN nanofibres can be used as the main polymeric precursor as the source of carbon [3,4]. Carbon nanofibres have great strength and stiffness as well as excellent electrical conductivity and thermal conductivity properties; consequently, they have been used in an assortment of applications in various fields, including
