Abstract

The present invention relates to a carbon nanostructure composite, the composite comprises carbon element and a first non-carbon and non-oxygen element material, the first non-carbon and non-oxygen element material is any one or a combination of at least two of first non-carbon and non-oxygen elements and compounds, and peak height ratio of carbon element G peak to carbon element D peak in a Raman spectrum of the composite is 1 to 20, the first non-carbon and non-oxygen elements in the composite are P, Si, Ca, Al and Na, the mass percentage of the first non-carbon and non-oxygen elements is 0.5-4wt%, and the far-infrared detection normal emittance of the composite is greater than 0.85. The composite has far infrared performance and antibacterial bacteriostat properties more obvious than that of the prior art, the composite is simple in preparation method and operation, some non-carbon and non-oxygen elements are retained by control of temperature-programmed stepping temperature and insulation temperature, and more excellent far infrared effect and antibacterial bacteriostat effect can be obtained.

Description

technical field [0001] The invention relates to the field of nanomaterials, in particular to a composite of carbon nanostructures and a preparation method thereof. Background technique [0002] Carbon nanomaterials refer to carbon materials with at least one dimension of the dispersed phase smaller than 100nm. The dispersed phase can be composed of either carbon atoms or heteroatoms (non-carbon atoms), or even nanopores. Nanocarbon materials mainly include carbon nanotubes, carbon nanofibers, nanocarbon spheres and graphene. [0003] The application of carbon nanomaterials is usually applied in the form of composite materials, that is, combined with other materials for application. There are two main ways of compounding carbon nanomaterials. [0004] One is to fully mix the substrates or monomers that carbon nanomaterials need to be compounded, and then carry out modeling by means of reaction, pouring, spinning, etc. To sum up, it is a method of compounding first and then...
