Abstract: PURPOSE: Non-covalent functionalized carbon nanotubes and a method for manufacturing the same are provided to improve the compatibility of the carbon nanotubes with respect to low polarity or non-polarity solvents or various polymers by coating the surface of the carbon nanotubes based on a lipophilic surface modifier. CONSTITUTION: An aromatic molecule with a carboxylic functional group is acylated to obtain an aromatic molecule with an acyl group(S1). The acyl group of the aromatic molecule is reacted with aliphatic amine to generate a lipophilic surface modifier(S2). The surfaces of carbon nanotubes are treated with the lipophilic surface modifier to be non-covalent functionalized(S3). The lipopilic surface modifier is an aromatic molecule in which an aliphatic chain is connected by an amide bond. The aromatic compound of the aromatic molecule is selected from pyrene, porphyrin, and the derivatives of the same.
