Abstract:

Activated carbon fibres with a diameter lower than 1 µm from electrospun polyacrylonitrile (PAN) fibre mat were obtained at developed optimal conditions of stabilisation, carbonisation and chemical activation processes. The fibres obtained were subjected to structural and chemical tests. A nonwoven fabric of activated carbon submicrofibres made from fibres electrospun from PAN/DMSO solution is characterised by very high nitrogen adsorption exceeding 900 cm3/g within the range of specific micropores, supermicropores and small mesopores, while the total volume of pores exceeds 1.4 cm3/g and the pore specific surface 2600 m2/g. The adsorption-desorption isotherm of nitrogen shows easy sorbate access to the inside of pores and its easy removal at the same time.
