Nanocomposite coated proppants and methods of making and use thereof

A method for producing proppants with a nanocomposite proppant coating, the method comprising:

• coating proppant particles with a surface modifier, a first resin, a coupling agent, a crosslinker, and a nano-reinforcing agent comprising both carbon nanotubes and graphene, to produce proppants with the nanocomposite proppant coating, wherein:
• the nanocomposite proppant coating comprises from 1 to 2 wt. % carbon nanotubes as calculated by weight of the first resin and from 1 to 2 wt. % graphene as calculated by weight of the first resin, in which the carbon nanotubes are connected to the graphene via sp2 covalent bonds, wherein:
• the nanocomposite proppant coating comprises from 2 to 3 wt. % carbon nanotubes and graphene combined as calculated by weight of the first resin;
• the surface modifier comprises an alkyl fluorosilane solution, a fluorinated surfactant, a fluorinated polymer, a fluorinated polymeric surfactant, or combinations of these;
• the coupling agent comprises at least one of 3-glycidoxypropyltrimethoxysilane, 3-aminopropyltriethoxysilane, 3-aminopropyltrimethoxysilane, and 3-chloropropyltrimethoxysilane;
• the crosslinker comprises at least one of hexamethylenetetramine, paraformaldehyde, oxazolidines, melamine resins, aldehyde donors, or resole polymers;
• the proppant comprises from 10 to 18 wt. % crosslinker as calculated by a weight of the first resin;
• and
• the proppant particle is a particle of a material comprising at least one of oxides, silicates, sand, ceramic, a second resin, plastic, mineral, glass, graded sand, treated sand, resin-coated sand, resin-coated particles, bauxite, sintered bauxite, glass particles, glass beads, and combinations of any of these.
