METHOD FOR PREPARING FLUORENE COPOLYMER BASED SILICA NANOPARTICLES

摘要

PURPOSE: A manufacturing method of fluorescent polymer based silica nano-particles is provided to form fluorescence polymer and core-shell nano-particles of silica which have uniform-size of 60-70 nano meters only through single step. CONSTITUTION: A manufacturing method of fluorescent polymer based silica nano-particles comprises the following steps: manufacturing silica shell shaped core-shell nano-particles of silica and fluorescent polymer core by mixing hydrophobic fluorescence polymer and silica precursor in a mixed solution of organic solvent, surfactant, and water; and obtaining core-shell nano-particles of the silica and fluorescent polymer by centrifuging the mixed solution, obtaining powders, and washing thereof. The hydrophobic fluorescent polymer is selected from PDDF, PFO, PFPV, and MEHPPV.
