Abstract

Carbon fibres (CF) have attracted huge interest due to their inherent properties, which make them useful for various applications. The majority of CF is produced from polyacrylonitrile, a type of synthetic polymer derived from ammonia and propylene. Herein, CF was synthesized via the electrospinning technique using lignin-based solutions. To enhance the electrospinning process of the lignin solution, a composite solution of natural polymers derived from lignin and cellulose acetate was employed. The resulting electrospun polymeric fibres exhibited diameters ranging from 100 to 250 nm. A two-step thermal treatment process was employed to stabilise and carbonise the polymeric fibres, transforming them into stable CF. The yield after carbonisation ranged from 16.5 to 24, depending on the applied carbonisation temperature. This reduction in mass was attributed to thermal-induced shrinkage, resulting in reduced CF diameters compared to the initial polymeric fibres. Raman analysis of the fibres revealed the CF modulus increasing reversely to the carbonisation temperature. Energy-dispersive X-ray spectroscopy (EDX) of the CF highlighted higher carbon content and diminished oxygen presence at elevated carbonisation temperatures. © 2023 IEEE.
