PREPARATION OF FUNCTIONALISED MATERIALS

摘要

The invention provides for a method of preparing a covalently functionalised carbon nanomaterial, comprising the steps of (i) treating a carbon material with a reducing agent comprising an alkali metal M in the presence of a solvent S to form a reduced-carbon material solution; and (ii) treating the resulting reduced-carbon material solution with a functionalising reagent to form a covalently functionalised carbon nanomaterial, wherein (a) the concentration of alkali metal [M] in step (i) is between 0.003 mol/L and 0.05 mol/L, and (b) the ratio of carbon material to alkali metal (C/M) in solution in step (i) is at least 2:1. A method of preparing a covalently functionalised carbon nanomaterial using N,N-dimethylacetamide as a solvent is also provided.
