Abstract
The invention discloses a kind of graphene preparation processes of surface modification, include the following steps：1）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；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.2）It takes the graphene dispersion of a small amount of MMA grafting in dimethylbenzene, obtains graphene suspension；It is filtered again with PTFE filter membranes, the graphene of surface modification can be obtained.Graphene surface can make UV coatings have preferable anti-static function by modification in the present invention.
Description
Technical field
The present invention relates to a kind of field of polymer composite material, especially a kind of graphene preparation process.
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
Preparation process.
The present invention is achieved through the following technical solutions technical goal.
The graphene preparation process of surface modification, includes the following steps：
1）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 leads to nitrogen return stirring 48 hours；Reaction solution is filtered after reaction terminating（Use the PTFE filter membranes of aperture 0.22um）, and
Vacuum drying oven room temperature is dried after being rinsed repeatedly with excess ethyl alcohol, obtains the graphene of MMA grafting.
2）It takes the graphene dispersion of a small amount of MMA grafting in dimethylbenzene, obtains graphene suspension；Again use PTFE filter membranes into
Row filters, and the graphene of surface modification can be obtained.
Compared with prior art, the present invention having the positive effect that：Graphene surface can make UV coatings by modification
With preferable anti-static function.
Specific implementation mode
With reference to embodiment, the invention will be further described.
The graphene preparation process of surface modification, includes the following steps：
1）Graphene powder is added in DMF first, MMA monomers and DCC is added in ultrasound after one hour；It is then heated to 90 °
