Abstract:

An analysis was carried out concerning the influence of coagulation bath temperature on the porous structure and the sorption & strength properties of polyacrylonitrile (PAN) fibres which include montmorillonite (MMT). We stated that fibres formed at a temperature of 25 °C were characterised by maximum tenacity at the level of 19 cN/tex. Obtaining fibres with increased total pore volume up to 0.34 cm3/g, which is beneficial for the medical purposes of the carbon fibres obtained from the PAN fibres discussed, requires the solidification process to be conducted in a coagulation bath at a temperature of 35 °C.
