Preparation, Morphology, and Application of Monodisperse Polymeric Spheres

摘要: Hydrogels have become increasingly important for a broad range of applications include contact lenses,1 and other medical devices,2 as intelligent supports the release low levels additives including perfumes,3 foodstuff thickeners. In addition to providing an inert matrix many applications, some hydrogel polymers respond environment so are used in ‘smart’materials devices. For example, gels based on certain substituted acrylamides show lower critical solution temperature4, can exhibit substantial volume change function temperature. Poly(N-isopropyl acrylamide) undergoes major transition at about 32°C5 is domestic applications.
