Description
Technical field
The present invention relates to Graphene modified paint, in particular, layer/polyaniline conductive coating of a kind of Graphene modification and preparation method thereof.
Background technology
Electrically conducting coating is a kind of new type functional coating, has the conductive characteristic of transmission current and eliminating accumulation static charge, is widely used in the functional areas such as protection against corrosion, radioprotective, anti-electrostatic, stealth material, conductive film.Being distributed in high polymer system by conducting particles by covalent linkage or non covalent bond even action, after superpolymer solidification, making the formation conductive network that contacts with each other between conducting particles, is a kind of method effectively directly preparing conductive coating.
Polyaniline is typical conducting polymer composite, has special electricity, optical property, can have electroconductibility after doping.Due to its structure diversification, good, the easy processing of environmental stability, cheap and become the study hotspot of conductive polymers.In addition, polyaniline has excellent absorption property to matching stain, metal ion, organic exhaust gas etc.Polyaniline, after certain process, can obtain various equipment and the material with specific function, as can be used as selective membrane material, anti-electrostatic and electromagnetic shielding material, electro-conductive fiber, impregnating material etc.
In the material of existing preparation containing the coating of polyaniline, polyaniline padding all have employed the polyaniline of protonic acid doping.The polyaniline of protonic acid doping is the most frequently used electrically conducting coating, but its dissolution rate is in a solvent extremely low, and easily oxidized, and thus color can change rapidly, and the change of color also illustrate that polyaniline there occurs dedoping, surface resistivity can increase gradually along with the solidification process of coating; In addition, low dissolution rate also can cause the polyaniline of protonic acid doping to reunite in resin matrix, thus comes off from substrate.
Therefore, there is the problem that bonding properties is poor, work-ing life is lower of conductivity deficiency, coating and matrix in existing polyaniline anti-corrosive paint.
Summary of the invention
The object of the invention is the problem that bonding properties is poor, work-ing life is lower in order to overcome existing polyaniline anti-corrosive paint conductivity deficiency, coating and matrix, and provide layer/polyaniline conductive coating of a kind of Graphene modification and preparation method thereof.
The present invention one technical scheme is as follows: a kind of layer/polyaniline conductive coating of Graphene modification, and it comprises the component of following mass ratio;
