제목 Preparation and application of thermo-sensitive hydrogel nano/microcapsules by microencapsulation using surface-treated silica particles as templates
초록 To modify the surface of the silica, 3-methacyloxypropyltrimethoxysilane (MPS) was added to the silica. Potassium persulfate (KPS) and sodium p-styrenesulfonate (NaSS) were added in the modified silica as initiator and ionic co-monomer,respectively. N-isopropylacrylamide (NIPAm) monomer was added and reaction was carried out. The silica/PNIPAm core-shell were prepared by using the method of electrostatic repulsion. The core-shell composite particles were soaked in HF solution to remove the silica core. PNIPAm hydrogel were applied to PES membranes. PES-PNIPAm hydrogel membranes were prepared.
