Research on Certain Electrophysical Properties of Sulfonated Carbon Fibers,
Abstract
The authors investigated the electrophysical properties of carbon fibers, obtained as a result of the pyrolysis of chemically modified cellulose and possessing cation-exchanging properties. The effect of the sulfonation of a carbon fiber on its electroconductivity was studied in connection with the fact that sulfonation increases the surface of the carbon fiber and, therefore, can affect the general electroconductivity of the fiber because of surface conductivity. On the other hand, the conductivity can increase because of the introduction of sulfogroups and carboxyls as ionogenic and electronegative groups. On the basis of these ion-exchanging fibers, materials containing metals - copper, nickel, sodium, cobalt - are obtained by ion-exchanging sorption from aqueous solutions. The electroconductivity of these materials was studied both without further heat treatment and without the products of their pyrolysis at 700-900C in vacuum.
