Abstract:

Graphene oxide/carbon nanotubes (GO/CNTs), as ideal carbon nanomaterials, have unique three-dimensional spatial structure and huge specific surface area, and are widely used in reinforcing polymer materials, which can improve the physical mechanical properties and stability of composite materials, and endow the composites with excellent thermal conductivity, electrical conductivity and dynamic mechanics, etc. In this paper, the preparation methods commonly used for the preparation of GO/CNTs bases are introduced, and the microscopic morphology, advantages and disadvantages of the composites prepared by the casting/coating method, the vacuum filtration method and the blending method are compared. The relationship between structural control and the properties of GO/CNTs-based composites is discussed. The modification of GO and CNTs, and the compatibility of GO/CNTs doping with polymer materials are introduced in detail. And its application in epoxy resin, rubber and biodegradable polymer is analyzed to explore the effect of GO/CNTs on the physical mechanical properties and functionality of composites. Finally, the technical advantages and current problems of GO/CNTs modified polymer materials are summarized, and the future development direction is prospected in order to provide a reference for the preparation of high value-added products from GO/CNTs modified epoxy resin, rubber and other polymer materials.
