Problems solved by technology

[0002] In the past 10 years, there have been a large number of reports on the composite of GO and various substrates at home and abroad, but it is not clear whether graphene oxide can achieve single-sheet exfoliation, and it can only be called GO / polymer intercalation composite material.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a graphene oxide reinforced vinyl ester composite material and a preparation method thereof. Background technique [0002] In the past 10 years, there have been a large number of reports on the composite of GO and various substrates at home and abroad, but it is not clear whether graphene oxide can achieve single-sheet exfoliation, and it can only be called GO / polymer intercalation composite materials. After 2004, with the confirmation of the stable existence of graphene monoliths in ordinary environments, and the mature application of mechanical exfoliation of GO to prepare graphene oxide, the synthesis of graphene oxide / polymer nanocomposites was truly realized. . [0003] Similar to single-walled carbon nanotubes (SWCNTs), graphene has excellent thermal, mechanical, and electrical properties. However, it is difficult for polymer molecules to enter the inner surface of SWC...
