Abstract
The invention discloses a kind of graphene surface covalent bond method of modifying, and graphene powder is added in DMF first, and MMA monomers and DCC is added in ultrasound after one hour；It is then heated to 90 °C of logical nitrogen return stirrings 48 hours；Reaction solution is filtered after reaction terminating（Use the PTFE filter membranes of aperture 0.22um）, vacuum drying oven room temperature is dried after being used in combination excess ethyl alcohol to rinse repeatedly, obtains the graphene of MMA grafting.The present invention can make UV coatings have preferable anti-static function.
Description
Technical field
The present invention relates to a kind of field of polymer composite material, especially a kind of graphene surface method of modifying.
Background technology
Graphene is applied in UV coatings, UV coatings can be made to have anti-static function, but graphene surface is without repairing
Decorations are difficult to obtain ideal effect.
Invention content
In view of the deficiencies of the prior art, the present invention proposes a kind of graphenes that UV coatings can be made to have preferable anti-static function
Surface covalent bond method of modifying.
The present invention is achieved through the following technical solutions technical goal.
Graphene surface covalent bond method of modifying, thes improvement is that：Graphene powder is added in DMF first,
MMA monomers and DCC is added in ultrasound after one hour；It is then heated to 90 °C of logical nitrogen return stirrings 48 hours；To anti-after reaction terminating
Liquid is answered to be filtered（Use the PTFE filter membranes of aperture 0.22um）, vacuum drying oven room temperature is dry after being used in combination excess ethyl alcohol to rinse repeatedly
It is dry, obtain the graphene of MMA grafting.
Compared with prior art, the present invention having the positive effect that：Graphene surface is modified using covalent bond, can be made
UV coatings have preferable anti-static function.
Specific implementation mode
With reference to embodiment, the invention will be further described.
Graphene powder, is added in DMF by graphene surface covalent bond method of modifying first, and ultrasound adds after one hour
Enter MMA monomers and DCC；It is then heated to 90 °C of logical nitrogen return stirrings 48 hours；Reaction solution is filtered after reaction terminating（Make
With the PTFE filter membranes of aperture 0.22um）, vacuum drying oven room temperature is dried after being used in combination excess ethyl alcohol to rinse repeatedly, obtains MMA grafting
Graphene.
