Preparation method of needle type metal -silica aerogel composite particle and needle type metal-silica aerogel composite particle prepared by the same

摘要

The present invention relates to a method for producing a needle-shaped metal-silica airgel composite particle and a metal-silica airgel composite particle prepared thereby, wherein the scattering rate of the needle-like metal-silica airgel composite particle prepared by using a sulfate solution as an acidic solution is An object of the present invention is to provide a method for producing needle-shaped metal-silica airgel composite particles that can be improved and the impact strength of a polymer resin can be improved when applied as an additive to a polymer resin. In addition, needle-shaped metal-silica airgel composite particles can be manufactured within a short time under mild conditions of low temperature and atmospheric pressure, so the process is simpler than the conventional manufacturing method, and the production cost is reduced, thereby improving productivity and economic efficiency.
