Investigation of internal microstructure and thermo-responsive properties of composite PNIPAM/silica microcapsules
Original language description
Composite microcapsules consisting of a thermo-responsive hydrogel poly-N-isopropylacrylamide (PNIPAM) and coated by silica (SiO(2)) nanoparticles have been synthesized by the inverse Pickering emulsion polymerization method. The composite capsules, whose mean diameter is in the 25-86 microm range in the expanded state, were characterized by static light scattering, atomic force microscopy (AFM), scanning electron microscopy (SEM), and laser scanning confocal microscopy (LSCM). It is reported that the hydrogel surface is uniformly covered by a monolayer of silica nanoparticles and that depending on the capsule size and degree of polymer cross-linking, either hollow-core or partially-filled hydrogel-core microcapsules can be created. Equilibrium thermo-responsive behavior of the composite microcapsules is investigated and it is found that after heating the particles above the lower critical solution temperature (LCST) of PNIPAM, the shrinkage ratio V/V(max) varies from 0.8 to 0.4 for a
