Polymer composite comprising metal based nanoparticles in a polymer matrix

摘要

A composite having a substrate and a plurality of core-shell nanoparticles. The substrate has microporosity, nanoporosity, or free volume and is a polymer matrix, a metal-organic framework, a micro-porous structure, or a nano-porous structure. The plurality of core-shell nanoparticles each has a core and at least one shell layer. The core is made from a decomposed product of a first precursor disposed in the microporosity, nanoporosity, or free volume of the substrate. The at least one shell layer is made from a decomposed product of a second precursor and is disposed on the core.

1. A method of forming a composite, the method comprising:
combining a first precursor and a substrate via at least one of diffusion, absorption, and adsorption; forming a nanoparticle core through decomposition of the first precursor and nucleation of a decomposition product of the first precursor; and forming a shell layer of at least a second material through at least one of diffusion, absorption, or adsorption of at least a second precursor followed by decomposition, and nucleation of at least one shell layer on the nanoparticle core to form a core-shell nanoparticle in the substrate; wherein the substrate has at least one of microporosity, nanoporosity, or free volume, and the first precursor and the second precursor are decomposed in-situ to form the nanoparticle core and shell layers.
