Hindered piperidine derivative functionalized silicon nanoparticles

Abstract

A composition contains silicon nanoparticles that have hindered piperidine derivative free radical scavengers on the surfaces of the silicon nanoparticles. A process for making silicon nanoparticles with hindered piperidine derivative free radical scavengers on the surface of the silicon nanoparticle, the process includes producing silicon nanoparticles using a VHFLPP process that collects silicon nanoparticles in a capture fluid as they are made and wherein hindered piperidine derivative free radical scavengers are provided in the capture fluid prior to, during and/or after collecting silicon nanoparticles so that the silicon nanoparticles and hindered piperidine derivative free radical scavengers are present in the capture fluid together.
