In this work, to fabricate sub 10 micrometer-sized microgels, we have developed a simple and facile method for the preparation of crosslinked microgels using a microdroplet generation system. The large number of stimuli-responsive poly(N-isopropylacrylamide) microgels with uniform size and shape can be prepared through photo-polymerization in oil of aqueous monomer droplets ejected from a microdroplet generators. The fabricated microgels as small as 8 μm in diameter was reduced to ~5.7 μm as increase of temperature above lower critical solution temperature. Furthermore, we demonstrated the functional materials such as fluorescent moieties and photothermal graphene oxide, stably incorporated in polymer matrices with developed system. |
