▎ 摘　　要

NOVELTY - Nanostructured carbonaceous compound comprises graphene, amorphous carbon and non-carbon non-oxygen element. The non-carbon non-oxygen element contains iron, silicon and aluminum. The content of non-carbon non-oxygen element is 0.5-6 wt.% of compound. USE - Nanostructured carbonaceous compound of polymer material used in field of knitting, bedding, household, automotive products, furniture, pipes, profiles and clothing (all claimed). ADVANTAGE - The excellent far infrared effect and antibacterial effect are obtained by controlling the content of non-carbon non-oxygen element in the compound. The normal emission rate of far infrared properties is 0.85 or more. The antibacterial rate is more than 95%. The nanostructured carbonaceous compound is applied in polymer material in case of low adding amount for modification of polymer materials. The need to carry out preliminary modification and activation processing is eliminated. The significant far infrared performance and antibacterial and bactericidal properties are achieved. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation method of nanostructured carbonaceous compound, which involves carrying out catalytic treatment of biomass carbon source under action of catalyst to obtain precursor, carrying out heat insulation of precursor at 140-180 degrees C for 1.5-2.5 hours under condition of protective gas to obtain first intermediate, raising first intermediate temperature to 350-450 degrees C for 3-4 hours of heat insulation under condition of protective gas, obtaining second intermediate, raising second intermediate temperature to 1100-1300 degrees C for 2-4 hours of heat insulation under condition of protective gas, obtaining third intermediate and sequentially washing third intermediate by alkali, acid and water.
