Abstract
A method of forming a composition having exfoliated nanoplatelets functionalized with covalently bound surface-modifiers, includes exfoliating a layered nanoclay is exfoliated with a surfactant. The method also includes reacting the exfoliated layered nanoclay with a surface modifier comprising one or more of an epoxide, a silane, or an isocyanate.
Claims4
A composition comprising exfoliated zirconium phosphate nanoplatelets functionalized with covalently bound surface-modifiers,
- wherein the composition comprising the exfoliated zirconium phosphate nanoplatelets functionalized with covalently bound surface-modifiers is formed by removing a surfactant from a suspension comprising the exfoliated zirconium phosphate nanoplatelets and replacing the surfactant with a hydroxyl-reactive moiety,
- wherein the covalently bound surface-modifiers are derived from one or more of cyclohexene oxide, 1,2-epoxy-3-phenoxypropane, or dodecyl/tetradecyl glycidyl ether.
A mixture, comprising:
- a composition comprising exfoliated zirconium phosphate nanoplatelets functionalized with covalently bound surface-modifiers, the composition comprising the exfoliated zirconium phosphate nanoplatelets functionalized with covalently bound surface-modifiers being formed by removing a surfactant from a suspension comprising the exfoliated zirconium phosphate nanoplatelets and replacing the surfactant with a hydroxyl-reactive moiety,
- wherein the covalently bound surface-modifiers are derived from one or more of cyclohexene oxide, 1,2-epoxy-3-phenoxypropane, or dodecyl/tetradecyl glycidyl ether, and
- an organic medium comprising one or more of a polymer or a solvent,
- wherein the composition is in a lyotropic suspension in the organic medium.
