CORE-SHELL SILICA NANOPARTICLES AND PRODUCTION METHOD THEREOF, HOLLOW SILICA NANOPARTICLE PRODUCTION METHOD USING SAME, AND HOLLOW SILICA NANOPARTICLES OBTAINED BY SAID PRODUCTION METHOD

摘要

The present invention relates to core-shell silica nanoparticles which, given a copolymer (A) comprising an aliphatic polyamine chain (a1) having a primary amino group and/or a secondary amino group and a hydrophobic organic segment (a2), are characterized by having a core layer, which has the hydrophobic organic segment (a2) portion of said copolymer (A) as the main component, and a shell layer, which comprises a composite having the aforementioned aliphatic polyamine chain (a1) and silica (B) as the main components, and by being monodisperse. The present invention further relates to: a production method of said core-shell silica nanoparticles; hollow silica nanoparticle production method using the same; and hollow silica nanoparticles obtained by said production method.
