Abstract
Amine functionalized nanoparticles having improved thermal and brine stability comprising a core-shell nanoparticle morphology comprising a trialkoxyorganosilane coated nanoparticle core and an amine functionalized group on the surface of the nanoparticle as a shell are disclosed. Methods and applications of use of the amine functionalized nanoparticles and compositions comprising the amine functionalized nanoparticles dispersed in an aqueous medium are also disclosed.
