METHOD OF PREPARING SILICA/POLYRHODANINE CORE/SHELL NANOPARTICLE VIA DISPERSION POLYMERIZATION

摘要

PURPOSE: A producing method of silica/polyrhodanine core-shell nanoparticle using the dispersion polymerization is provided to easily obtain polyrhodanine from the surface of a silica nanoparticle. CONSTITUTION: A producing method of silica/polyrhodanine core-shell nanoparticle comprises the following steps: dispersing silica into a solvent, and adding an initiator into the solvent for absorbing the initiator to the surface of the silica; drying silica nanoparticles absorbed with the initiator, and dispersing into another solvent; injecting a rhodanine monomer into the solvent containing the silica nanoparticles absorbed with the initiator for inducing the polymerization on the surface of the silica; and precipitating the solvent for collecting the silica/polyrhodanine core-shell nanoparticle.
