Abstract
Cutting elements for earth-boring tools may include a substrate and a polycrystalline diamond table secured to the substrate. At least a portion of the polycrystalline diamond table may be formed from a plurality of core particles comprising a diamond material and having an average diameter of between 1 μm and 500 μm. A coating material may be adhered to and covering at least a portion of an outer surface of each core particle of the plurality of core particles, the coating material being an amine terminated group. A plurality of nanoparticles selected from the group of carbon nanotubes, nanographite, nanographene, non-diamond carbon allotropes, surface modified nanodiamond, nanoscale particles of BeO, and nanoscale particles comprising a Group VIIIA element may be adhered to the coating material.
