제목 Preparation of NIPAm-based hydrogel nano/microcapsules and their morphology and thermoresponsive behavior
초록 The silica core composite particles with poly(N-isopropylacrylamide) (PNIPAm) hydrogel shell were prepared by using silica nano/micro particle templates which were modified with 3-methacyloxypropyltrimethoxysilane. The thermo-responsive PNIPAm hydrogel nano/microcapsules were prepared by soaking the core-shell composite particles in hydrofluoric acid solution. The lower transition temperature (LCST) of hydrogel was controlled by the addition of hydrophobic comonomer N-butoxymethyleneacrylamide (nBMA) and the higher transition temperature of hydrogel was obtained by the addition of hydrophilic comonomer acrylamide (AAm).
