METHOD FOR MODIFYING SURFACE OF MATERIAL MADE OF POLYPROPYLENE

摘要

FIELD: polymers. ^ SUBSTANCE: invention relates to a method for modifying a material surface made, in particular, of polypropylene. Method involves activation of material surface by effect of glow charge between aqueous solution and anode located over aqueous solution under atmosphere pressure, treatment of activated surface in a macroheterocycle solution and washing out from its excess. Activation of material surface and treatment of activated surface are carried out simultaneously in an aqueous solution of cobalt phthalocyanine disulfoacid in its concentration 0.3-0.6 g/l for 15-30 min and washing out is carried out in sodium hydroxide aqueous solution in the concentration 0.07-0.1 g/l. Invention provides enhancing the catalytic activity of modified material up to 70%, decreasing time for the activation process up to 30 min and enhancing ecological safety of the process. ^ EFFECT: improved modifying method. ^ 1 tbl
