Abstract

The present invention provides a carbon-nanostructure-containing compound comprising graphene, amorphous carbon and a non-carbon non-oxygen element, and the non-carbon non-oxygen element accounts for 0.5wt%-6wt% of the compound. Through controlling of content of the non-carbon non-oxygen element in the carbon-nanostructure-containing compound, excellent far infrared effect and antibacterial bacteriostat effect can be obtained, far-infrared property normal emittance can reach 0.85 or more, and the bacteriostasis rate can reach more than 95%. At the same time, the carbon-nanostructure-containing compound can be used in a high-molecular material in a lower amount for modifying of the high-molecular material without pre-modification and activation for achievement of significant far-infrared and antibacterial bactericidal properties.
