| titleOfInvention | Method of modifying surface property of silica powder using non-aqueous vapor deposition and method for silica-metal core-shell complex |
| abstract | The present invention relates to a method for modifying a surface of silica powder and a method for preparing a silica-metal core-shell composite using a solvent-free vapor deposition method, and specifically, 1) placing a silica particle powder and a silane coupling agent inside a reaction vessel; 2) maintaining the reaction vessel under vacuum; And 3) a method for modifying the surface of silica powder using a solvent-free vapor deposition method including heat-treating the reaction vessel in a vacuum oven at 100 to 150°C, and the surface modified It provides a silica-metal core-shell composite manufacturing method comprising the step of coating a metal on the surface of the silica particles by using an electroless plating method of the silica particles. The method for preparing a silica-metal core-shell composite according to the present invention is a self-assembled monomolecular film of -SH (thiol) and -NH 2 (amine) functional groups on the surface of silica particles using a vapor deposition method that does not use any solvent on the surface of the silica particles. Silica surface modification is possible through formation, and inexpensive silane coupling agent materials and process conditions applicable to industrial sites were derived and optimized. |
