Filling with the Graphene Nanoplates as a Way to Improve Properties of Epoxy-Composites for Industrial and Geophysical Machinery

It is established that the filling with graphenes increases (by 1.3-1.8 times) the strength at normal adhesion to steel. At same time, filling reduces the compressive strength and abrasion resistance and also resistance to aggressive liquids (conc. nitric acid, chloromethylene; mixture acetone-ethylacetate). The most probable reason for this may be the features of the graphene plate structure, prone to deactivation (self-rotation) of particles and therefore sensitive to the technology of hardening. Studies have shown the limited positive effects of graphene as a filler of epoxydes, although its introduction can significantly improve certain practical characteristics (adhesion, thermal and electrical conductivity).
