Abstract
The invention discloses composition liquid used for stripping graphene. The composition liquid comprises the following components in parts by weight: 100 parts of an alcohols solvent, 3-20 parts of hydroxy acrylic resin, and 1-30 parts of flaky metal powder. By employing the flaky metal powder as a grinding medium, uniform stripping strength can be generated on a graphite flake layer, the flaky metal powder is cooperated with alcohols solvent capable of penetrating into the graphite flake layer as well as the hydroxy acrylic resin, a hydrogen bond is formed between the alcohols solvent and the hydroxy acrylic resin; the hydrogen bond is destroyed by the generated heat during a grinding process or through an external heating mode, so that an impact force is generated to a graphite layer, attacks from outside to inside is formed, and stripping for graphene can be effectively promoted. The composition liquid used for stripping graphene has the advantages of no corrosion on equipment, and no damage on a structure of graphene.
Description
Technical field
The present invention relates to Graphene production technical field, being specifically related to a kind of for graphite being peeled off the combination liquid for Graphene.
Background technology
Graphene is a kind of two-dimensional material with good flexibility, electrical property.You need to add is that, stricti jurise is said, Graphene is the lamellar of a kind of monolayer；But due to the preparation difficulty of single-layer graphene, generally also the form the few-layer graphene alkene with similar performance is also ranged in the category of Graphene.
At present, the method that prepared by Graphene mainly has: chemically grown method and physics stripping method.Low compared to efficiency, be not suitable for the chemically grown method of industrialized mass production; it is raw material that physics stripping method mainly adopts cheap graphite; make graphite layers peeling-off by graphite crystal is applied mechanical force; break the Van der Waals force of graphite layers; forming monolithic graphite alkene or form the few-layer graphene alkene, this physical separation methods has more industrial prospect and applicable large-scale production.
In Graphene stripping process, it is necessary to add some auxiliary agents, to increase the interlayer distance of graphite or so-called intercalation, so that graphite is peeled off better.As adopted nitric acid, potassium permanganate, chromic acid or hydrogen peroxide as oxidant, concentrated sulphuric acid, as intercalator, introduces the oxy radicals such as hydroxyl, epoxide group and carboxyl at graphite layers or edge, increase graphite layers from, be beneficial to follow-up graphite layers and peel off.But this chemical substance intercalated technique acid consumption is big, production process has the pollution of the harmful gass such as SOx, NOx or heavy metal ion, product there is sulfur remain, the Graphene finally given is easily generated defect, and in the application equipment there is is corrosion, reduce the service life of equipment, add production cost.
Summary of the invention
It is an object of the invention to overcome the defect existed in prior art, it is provided that a kind of Graphene peels off combination liquid, and this combination liquid cooperative mechanical is ground, it is possible to be efficiently peeled off graphite, and the structural deterioration of Graphene is little.
For realizing the purpose of the present invention, the technical scheme is that a kind of Graphene peels off combination liquid, the composition of this combination liquid includes:
Alcohols solvent 100 parts,
Hydroxylated acrylic resin 3～20 parts,
Flake metal powder 1～30 part；
Wherein, each component is in its parts by weight.
Preferred technical scheme is, described alcohols solvent is one or more in ethanol, normal propyl alcohol, n-butyl alcohol, propylene glycol and terpineol.
Preferred technical scheme is, described flake metal powder is one or more in zinc powder, nikel powder, argentum powder.
It is preferred that technical scheme be that described flake metal powder is of a size of 3～10 microns.
Preferred technical scheme is, the number-average molecular weight of described Hydroxylated acrylic resin is 10000～20000.
Prior art is compared, and Graphene of the present invention peels off combination liquid by adopting flake metal powder as abrasive media, it is possible to produce uniform peeling force on graphite flake layer；Flake metal powder coordinates the alcohols solvent and Hydroxylated acrylic resin that can penetrate in graphite flake layer, by forming hydrogen bond between alcohols solvent and Hydroxylated acrylic resin, grinding the heat produced or making hydrogen bond destroy by the mode of external heat, thus graphite linings is produced impulsive force, form inside and outside pincer attack, be effectively facilitated the stripping of Graphene.This combination liquid is being peeled off while Graphene, and not etching apparatus does not damage graphene-structured.
