Patent ID: 8414861

Claim:
A method of synthesizing a carbonized cellulose material having a graphite nanolayer on a surface thereof, comprising: i) heating a cellulose fiber in a reactor; ii) forming primary carbonized cellulose while maintaining temperature of the reactor; iii) cooling the formed primary carbonized cellulose; iv) heating the cooled primary carbonized cellulose; v) forming a secondary carbonized cellulose while maintaining temperature of the reactor; and, vi) cooling the formed secondary carbonized cellulose, wherein the graphite nanolayer is made from the primary carbonized cellulose through the consecutive heating and cooling of the primary carbonized cellulose, and wherein the iii) cooling of the primary carbonized cellulose comprises: a) cooling the primary carbonized cellulose to a temperature of 200° C. under a 100% hydrogen atmosphere; and b) cooling the primary carbonized cellulose to room temperature under a 100% nitrogen atmosphere.
