Abstract

In this chapter, the design, preparation, and performance of various monodisperse pH-responsive microgels with pH-responsive swelling/shrinking property or pH-responsive stability are introduced. Monodisperse pH-responsive chitosan microspheres and microcapsules with acid-triggered swelling and decomposition properties are developed using uniform-sized water-in-oil (W/O) emulsions as preparation templates via microfluidic approaches. Monodisperse cationic pH-responsive poly(N,N-dimethylaminoethyl methacrylate) (PDM) microgels are successfully prepared by dispersion polymerization in ethanol/water mixture using poly(vinyl pyrrolidone) (PVP) as the steric stabilizer. Monodisperse cationic pH-responsive PDM microcapsules are prepared via UV-initiated polymerization based on a double initiation system. These monodisperse pH-responsive microgels with good biocompatibility are of great potential as smart drug delivery carriers.
