Abstract: Embodiments relate to a proppant particle or a solid article that includes a proppant particle/solid article and one or more coatings on an outer surface of the proppant particle/solid article including one or more well treatment agents and one or more controlled release polymer resins. Each well treatment agent is at least one selected from the group of a scale inhibitor, a wax inhibitor, a pour point depressant, asphaltene inhibitor, an asphaltene dispersant, a corrosion inhibitor, a biocide, a viscosity modifier, and a de emulsifier. Each controlled release polymer resin is at least one selected from the group of a polyurethane based resin, an epoxy resin, a phenolic resin, and a furan resin.

Abstract: A composition comprising a phase separated block copolymer and an inorganic dielectric nanoparticle, wherein the nanoparticle is dispersed in the copolymer and is present primarily in one phase. For example, a Ti02 nanocomposite can be created via the in situ formation of Ti02 within a silane-grafted OBC. Taking advantage of the phase morphology of the OBC and the differential swelling of the hard and soft segments, due to their inherent crystallinity, enables the selective incorporation of Ti02 nanoparticles into the soft segments of the OBC.
