Filed: 2019-09-09
Abstract: The present invention relates to a method for surface modification of silica powder using a solvent-free vapor deposition process and a method for preparing a silica-metal core-shell complex. Particularly, the method for surface modification of silica powder using a solvent-free vapor deposition process includes the steps of: 1) introducing silica particle powder and a silane coupling agent into a reaction container; 2) allowing the reaction container to stand under vacuum; and 3) heat treating the reaction container in a vacuum oven at 100-150°C. In addition, the method for preparing a silica-metal core-shell complex includes a step of coating the surfaces of the surface-modified silica particles with a metal through an electroless plating process. The method for preparing a silica-metal core-shell complex allows surface modification of silica particles through the formation of a self-assembled mono-molecular film of -SH (thiol) and -NH_2 (amine) functional groups on the surface of silica particles by using a vapor deposition process using no solvent, wherein a cost-efficient silane coupling agent and processing conditions applicable to the industrial fields are derived and optimized.
