Description
Technical Field
The invention provides a production process of a carbon nanomaterial.
Background
The carbon nanomaterial mainly comprises fullerene, carbon nanotube, graphene and the like, and has wide application prospect due to unique structure and excellent mechanical, electrical, chemical and other properties. Wherein Graphene is a polymer of carbon atomsspThe two-dimensional carbon nanomaterial with hexagonal lattice and honeycomb lattice is excellent in optical, electrical and mechanical properties, has important application prospects in the aspects of materialization, micro-nano processing, energy, biomedicine, drug delivery and the like, and is considered as a revolutionary material in the future. Common methods for producing graphene powder are a micromechanical lift-off method, an orientation attached growth method, an epitaxial growth method, a graphite oxide reduction method and a Chemical Vapor Deposition (CVD) method.
Among them, the micro-mechanical exfoliation method is the simplest one, namely, separating graphene or graphene nanoplatelets from a graphite crystal by applying mechanical force to the graphite crystal. The method has the advantages of simple process, low preparation cost and high sample quality, but the method has some disadvantages, such as the obtained product is not easy to control in size, and graphene with enough length cannot be reliably prepared, so that the method cannot meet the industrial requirement.
Peter w.sutter et al used rare metal ruthenium as a growth substrate by an epitaxy method, and "seeded" with graphene using the growth substrate atomic structure. The single-layer graphene obtained by the method has satisfactory performance, but the graphene sheet produced by the method is often uneven in thickness, and the adhesion between the graphene and the matrix can influence the characteristics of the prepared graphene sheet.
The epitaxial growth method is to epitaxially grow a graphite layer on the surface of a single crystal and then peel the graphite layer from a substrate by chemical etching. There are two common methods, one is SiC surface decomposition and one is molecular beam deposition. Graphene with the thickness of 1-2 carbon atoms can be prepared by adopting an epitaxial growth method, but large-area graphene with uniform thickness is difficult to obtain.
The graphite oxide contains epoxy groups, hydroxyl groups, carbonyl groups, carboxyl groups and other oxygen-containing groups, and can be dissolved in water and certain organic solvents. Graphene can be produced by a graphite oxide reduction method. The method has the advantages of low cost, high efficiency, environmental protection and large-scale industrial production, but has the disadvantage of easily causing loss of some physical and chemical properties.
The chemical vapor deposition method is to deposit a layer of transition metal film (such as Fe, cu, ni, pt, au) as a substrate, make use of the high temperature solid solution of the transition metal film and C, then cool and separate out the transition metal film, and reconstruct the surface to form the graphene. The method has the advantages that the method is beneficial to preparing the graphene with larger area; the defects are that the number of layers is difficult to control accurately, metal substrate stripping and substrate transferring are needed, the cost is high, and the process is complex.
It follows that the production of carbon nanomaterials is mainly faced with several problems: the method can not continuously produce a large amount of carbon nano materials, has good quality and uneven product quality, has high product cost, can not be widely applied, has long production process and low efficiency.
