Abstract
Description
Technical Field
[0001] The invention relates to the technical field of graphite powders, in particular to a process method for a graphene high temperature resistant material. Background Art
[0002] At present, there are many studies on the three-dimensional (3D) forms of graphene nanomaterials such as aerogels, microporous or mesoporous frameworks and hydrogels generated by reactions. Graphene or graphene oxide, both of which contain π in the monoatomic layer flow, has been identified as a good modifier. Graphene or graphene oxide combined with elastomeric structures can add a variety of functional characteristics. Loading nanoscale metals on graphene can exhibit different functions in the electronic or magnetic fields. In previous studies, there have been studies on dissolved or dissolved graphene, such as nanodispersion. However, there are few reports on the study of functional multi-component interfaces during in situ reactions because monomers are difficult to distribute at the nanoscale level and the active effect cannot be well maintained.

[0007] S3, adding a catalyst into the zinc oxide-graphene oxide sol to react and generate a composite material.
[0008] Furthermore, the stirring speed in S1 is 10-16000 r / min.
[0009] Furthermore, the content of sodium tetrapropylene benzene sulfonate is 2% to 5% by weight of the mixed solution of zinc oxide particles and graphene oxide.
[0010] Further, under the conditions of a temperature of 80 to 100° C., a stirring speed of 20 to 9000 r / min, and a stirring time of 2 to 90 h, the activated graphene oxide nanosheets are dissolved in polyoxypropylene glycol, and stirred until the solution becomes viscous.
[0011] Furthermore, the reducing agent in S2 is a mixed solution of N2H4·H2O and NH3·H2O, and the molar ratio of N2H4·H2O to NH3·H2O is 1:(4-6).
