发明名称 METHOD FOR PREPARING NANOSIZED GRAPHENE PLATES HIGHLY DISPERSIBLE IN LOW-POLAR POLYMER MATRIXES AND RESPECTIVE POLYMER COMPOSITIONS
摘要 FIELD: chemistry.SUBSTANCE: invention can be used in chemical industry. Natural or synthetic graphite or thermally expanded graphite contacts to oxygen or ozone at a temperature of -30°C to 700°C. The produced precursor representing a graphite material functionalised by oxygen groups (FOG) with molar ratio of carbon/oxygen more than 8:1 is reduced by chemical or physical aids. The chemical recovery involves using water gas, hydrogen, hydrazine, and methyl hydrazine. The physical recovery involves heating to at least 600°C at a temperature gradient of more than 10°C a minute. The molar ratio of carbon/oxygen in the prepared nanosized graphene plates is more than 20:1.EFFECT: expandable thermoplastic polymer compound contains the thermoplastic polymer matrix; 1-10 wt % in relation to a polymer of the expanding agent; 0,004-15 wt % in relation to a polymer of the prepared nanosized graphene plates having high electric conductivity and dispersing ability in non-polar and low-polar polymers.9 cl, 1 dwg, 11 ex
