Description
Technical field
The present invention relates to technical field of metal, particularly to a kind of graphene-supported metallic composite and system thereof
Preparation Method.
Background technology
Along with the development of modern science and technology, this year, carbon nanomaterial has caused the concern of every subjects.Since 2004
University of Manchester utilizes mechanical stripping method to obtain Graphene one first, and it is always in carbon nanomaterial the focus of research.
Graphene is with sp by carbon atom2The monoatomic layer that hydridization connects is constituted, and is also called " mono-layer graphite sheet ", and its theoretic throat is only
0.35nm, be at present seen by the thinnest two-dimensional material.And Graphene is the elementary cell constituting other carbon nanomaterials.Stone
The theoretical specific area of ink alkene is high, and mechanical strength is high, good heat conductivity, and electron transport ability is strong, and it is excellent that electron mobility is big etc.
Point.So Graphene is excellent carrier or the ingredient of many materials.
Graphene and metal material are combined the Metal/grapheme composite that obtains can in conjunction with both advantages, one
Aspect Graphene can make metal material be uniformly dispersed, stable;On the other hand electric transmission rate can be strengthened, it is provided that composite
Overall performance.Just because of the good characteristic of Metal/grapheme composite, this material modified electrode, electrochmical power source,
Solaode, catalyst and the aspect such as pharmaceutical carrier and gas sensor have a wide range of applications.So this grinds
Study carefully and be intended to research a kind of novel graphene-supported metallic composite of discovery, to expect to have in various new technology fields
Significant progress and application prospect.
Summary of the invention
For solving above-mentioned technical problem, the present invention provides a kind of graphene-supported metallic composite and preparation side thereof
Method, by using specified raw material to be combined, coordinates corresponding production technology, has obtained a kind of graphene-supported metal composite
Material, its mechanical strength height, good heat conductivity, electron mobility are big, it is possible to meet the requirement of industry, before having preferably application
Scape.
The purpose of the present invention can be achieved through the following technical solutions:
Graphene-supported metallic composite, is prepared by the raw materials in: natural flake graphite 25-35 part, nitric acid
Sodium 5-10 part, potassium permanganate 3-5 part, sodium borohydride 4-8 part, hydrazine hydrate 2-5 part, Polyethylene Glycol 9-15 part, three oxidation four ferrum 2-6
Part, Nickel dichloride. 1-3 part, stannic chloride 1-3 part, potassium borate 5-9 part, tungsten powder 15-25 part, nikel powder 5-15 part, copper powder 3-9 part, magnesium powder
