Abstract

The invention discloses a preparation method of a polymer modified graphene composite material. The preparation method includes the steps: firstly, preparing graphite oxide in an ultrasonic radiationreactor into modified graphene by modifiers; secondly, dispersing the modified graphene into polymer emulsion to prepare stable polymer / modified graphene composite emulsion; thirdly, adding emulsion breakers into the composite emulsion to obtain polymer / modified graphene composite master batches; finally, adding the master batches, polymers and various auxiliary materials into an extruder, meltingthe materials at a certain temperature and extruding the materials to obtain the polymer / modified graphene composite material. Performances such as the tensile strength and the tensile modulus of thecomposite material are good, the preparation method is simple in preparation process, low in reaction temperature, easy to control and low in energy consumption, waste gas and waste liquid are avoided in the production process, and the preparation method is environmentally friendly.

Description

technical field

[0001] The invention belongs to the field of composite material preparation, and in particular relates to a preparation method of a polymer-modified graphene composite material. Background technique

[0002] Graphene is a new carbonaceous material with a two-dimensional honeycomb lattice structure formed by sp2 hybridized carbon atoms closely packed, with a thickness of one or more atomic layers, and can be divided into one or more layers according to the number of layers Graphene. Theoretical research on graphene has a history of more than 60 years, and until 2004, two-dimensional graphene sheets that can truly exist independently were obtained by Novoselov at the University of Manchester in the United Kingdom by using tape to peel off highly oriented graphite. So far, graphene has been prepared by the following methods: 1) chemical vapor deposition (Eizenberg M., Blakely J.M.Surf.Sci.1970, 82, 228-236.); 2) epitaxial growth (Berger C. Song Z., Li X., Wu X...
