Abstract

Marina V. Seregina. Two ways of the colloid formation of metals and metal oxides in the polyacrylonitrile (PAN) and its copolymer (1.5 wt % of itaconic acid) (PAN-I) have been studied. The thermal decomposition of W, Mo and Cr carbonyl complexes with PAN, prepared by the interaction of PAN nitrile groups with VI B group metal hexacarbonyls has been investigated. The thermolysis under air leads to a formation of metal oxide particles. For the Cr-containing PAN, the presence of dispersed Cr2O3 with a size less than 3 nm was estimated by ESR. Co-containing polymers were prepared by mixing Co2(CO)8 with PAN-I in DMF. It was found that Co2(CO)8 interacts with DMF giving salt [Co(DMF)6]2+[Co(CO)4]-2. By ferromagnetic resonance and SAXS, colloid size depends on thermolysis conditions and loading of the Co complex and varies from 1 to 10 nm.
