Abstract

The invention belongs to the technical field of materials, in particular to a carbon nanometer material with surface carboxyl functionalized, a preparation method of the carbon nanometer material and an application of the carbon nanometer material. The preparation method of the carbon nanometer material with surface carboxyl functionalized comprises the following steps: (1) preparing a fictionalization nanometer material including acyl chloride groups: adding 100 mg of carbon nanometer materials into 100 ml of a carboxylation accelerator, dispersing the materials in an ultrasonic mode, adding 2 g of acyl chloride and 3-5 g of a catalyst, reacting all the materials for 48-72 hours, filtering, and obtaining filter residue which is the fictionalization nanometer material including the acyl chloride groups; (2) preparing the carbon nanometer material with surface carboxyl functionalized: adding 100 mg of the fictionalization nanometer material including the acyl chloride groups, prepared in the step (1), into 100 ml of a acid solution with the concentration of 1 mol / L, dispersing the materials in an ultrasonic mode, stilling the materials, filtering, washing and drying filter residue, and obtaining the carbon nanometer material with surface carboxyl functionalized.

Description

technical field [0001] The invention belongs to the technical field of materials, and relates to a carbon nanomaterial and a preparation method thereof, in particular to a surface carboxyl-functionalized carbon nanomaterial, a preparation method and an application thereof. technical background [0002] Carbon nanomaterials refer to carbon materials with at least one dimension of the dispersed phase smaller than 100nm. The dispersed phase can consist of either carbon atoms or heteroatoms (non-carbon atoms), and can even be nanopores. Carbon nanomaterials mainly include four types: graphene, carbon nanotubes, carbon nanofibers, and carbon nanospheres. [0003] (1) Graphene: Graphene is a new material with a single-layer sheet structure composed of carbon atoms. It is a flat film composed of carbon atoms in a hexagonal honeycomb lattice, with a thickness of only one carbon atom. [0004] (2) Carbon nanotubes: Carbon nanotubes are seamless, hollow tubes rolled from graphite s...
