METHOD FOR PREPARING PLATE-TYPE METAL-SILICA COMPOSITE AEROGEL AND PLATE-TYPE METAL-SILICA COMPOSITE AEROGEL PREPARED THEREBY

Document Type and Number:

WIPO Patent Application WO/2018/169155

Kind Code:

A1

Abstract:

The present invention relates to a method for preparing a plate-type metal-silica composite aerogel and a plate-type metal-silica composite aerogel prepared thereby. More specifically, the present invention provides: a method for preparing a plate-type metal-silica composite aerogel, wherein plate-type metal-silica composite aerogel particles can be produced in low-temperature and normal-pressure conditions in a short time by first forming a plate-type intermediate through the regulation of the concentration of a metal salt and the concentration of a basic catalyst and then adding an appropriate amount of a water glass solution thereto, so that the preparation method of the present invention achieves simple processes, reduced production costs, and excellent economical feasibility compared with a conventional preparation method; and a plate-type metal-silica composite aerogel, which is prepared by the preparation method of the present invention, has excellent dispersibility, and requires no additional surface modifier.
