摘要: A simple and efficient method is developed to fabricate monodisperse fast-responsive poly(N-isopropylacrylamide) (PNIPAM) microgels with open-celled porous structure. First, numerous fine oil droplets are fabricated by homogeneous emulsification then evenly dispersed inside PNIPAM as porogens via the combination of microfluidic UV-initiated polymerization methods. Subsequently, embedded squeezed out upon stimuli-induced rapid volume shrinkage microgels; a result, spongelike structure formed microgels. The provides interconnected free channels for water transferring convectively inward or outward during phase transition process therefore, response rates much faster than that normal ones in both the...
