Method for preparing ferrocene functionalized carbon nanotube composite material

Abstract

The invention discloses a method for preparing a ferrocene functionalized carbon nanotube composite material through thiol-ene click chemistry. The method comprises the following steps: through an acid oxidation modification method, performing carboxyl functionalization on the surface of a multi-walled carbon nanotube; performing sulfydryl modification on the surface through amidation with aminothiol; and selecting an appropriate ferrocene derivative with carbon-carbon double bonds to prepare the ferrocene functionalized carbon nanotube composite material through thiol-ene click chemical reaction. The method is mild in reaction condition and simple and convenient in process; and the prepared ferrocene functionalized carbon nanotube composite material has good dispersion uniformity, stability, conduction reversibility, electric catalytic property and biocompatibility, is low in cost, and can be applied to conductive materials, chemical and biological sensors, biological analysis and other fields as a novel functionalized nanocomposite material.
