Abstract
FIELD: electronics. SUBSTANCE: chemisorption fiber containing carboxylic or nitrogen-containing groups is treated with aqueous solution of transient metal salts or theirs mixture. Concentration of solution are 10-10M M. Metals are selected from the group: copper, iron, cobalt, nickel. Additionally, treatment with 10-10M aqueous solution of sodium sulfide is carried out. In the case of mixtures treatment mixtures of iron with cobalt or copper salt at ratio (1-3) : (2-4) or copper with cobalt salt at ratio (2-4) : (1-3) are used. EFFECT: improved method of modification. 3 tbl
