ONE-POT SYNTHESIS OF SILICA NANOPARTICLE IN SILICA NANOTUBE NANO-STRUCTURE

摘要

PURPOSE: A manufacturing method of silica nanotube and nanoparticle is provided to manufacture a nanotube and nanoparticle at the same time through one step process by using a surfactant solution and a vapor deposition reaction. CONSTITUTION: The manufacturing method of silica nanotube/nanoparticle includes following steps.(a) The surfactant solution 'capable of forming a nanoparticle structure' and an acid solution generating a hydrolysis- condensation reaction of a silica precursor are mixed. The surfactant solution is manufactured.(b) The surfactant solution is introduced to a hard template.(c) The silica precursor is reacted to the hard template, in which 'the surfactant solution is introduced' through the vapor deposition method. The silica nanotube / nanoparticle structure is manufactured with the one step process.(d) The silica nanotube / nanoparticle is obtained by eliminating the hard template. The kind of the surfactant is P65, P84, P103, P123 and their mixture.
