Abstract
Cu-C nanocomposites were obtained during the infrared pyrolysis of a precursor based on polyacrylonitrile and copper acetate. In such nanocomposites, Cu particles were dispersed in the graphitelike carbon matrix. Cu nanoparticle sizes were from 15 to 20 nm and did not depend on the preparation temperature in the range 300–600°C. At T = 700–800°C, the average size of Cu nanoparticles increased to 40 nm. In this case structuring of the carbon phase was observed.
