Conclusions
-- The primary adsorption center content of modified ÉLUR-M carbon fibres depends on the conditions of the surface activation process: after electrochemical treatment, more of them are contained than after treatment with ozone.
-- In electrochemical treatment of carbon fibres, an optimum zone of intensity of this process is observed, for which the formation of the largest number of active centers is characteristic.
-- The number of active centers which are formed on the surface of type LU carbon fibres depends on the final pyrolysis temperature and is caused by structural—chemical processes during carbonization of the material.
-- The investigated carbon fibres are ultramicroporous materials with a pore diameter no greater than 6–7 Å and a total pore volume of 0.03–0.09 cm3/g.
