Description
Technical field
It is particularly a kind of to be situated between using graphene modified metal is conductive the present invention relates to nanometer enhanced type composite material field
Matter, electric conductivity and intensity are significantly improved while save graphene denatured conductive cement and its preparation of graphene raw material
Method.
Background technology
Electroconductive cement is because have all characteristics of cement, while have electric conductivity concurrently again, and its application is wide, and it was both
It can play a part of shielding radio interference, defence electromagnetic wave with alternative metals；And can is used as electrical material, as earthing or grounding means,
The lightning protection of building, the switching-on resistance of breaker, eliminate electrostatic equipment, metallic cathode protection system etc.;It can also utilize
Fuel factor caused by conduction carries out the melting ice and snow on environment heating, building and heating and road and airport；At the same time it can also utilize
A kind of alert and resourceful intellectual material etc. is made in its one electric correlation properties of power.Conductive cement base material is in ordinary cement sill
Add conducting medium, conductive path formed by being cross-linked with each other between conducting medium so as to reach conductive function, for
The conducting medium of conducting concrete processed typically has following several classes：Graphite, carbon fiber, slag, steel fibre, carbonaceous aggregate, carbon black etc.,
Cement and conductive performance can be reached by adding the electroconductive cement that such conducting medium is produced, but because staying in common material,
High conductivity and high strength of cement can not be accomplished simultaneously.

The high electron mobility of black alkene (~ 23000cm2/ (V s)), high heat conductance (~ 5000W/ (m K)) make it in conductive and heat-conductive material
Material field has broad application prospects, and area is that 1m2 graphene synusia can bear 4 kg quality, and its intensity is about common
100 times of steel, the packaging bag made of graphene, about 2 tons of weight can be born, be the material for the maximum intensity being currently known
Material, its electron mobility can reach 2 × 105cm2/Vs, 140 times of electron mobility about in silicon, 20 times of GaAs, temperature
It is high to spend stability, for electrical conductivity up to 108 Ω/m, surface resistance is about 31 Ω/sq（310Ω/m2）, it is lower than copper or silver, it is room temperature
The best material of lower conduction.
Due to the good characteristic of graphene, therefore it is applied to the production of electroconductive cement, such as application number by professional
201310098136.6, entitled " graphene oxide and graphene enhancing cement-base composite material and preparation method thereof ",
