摘要: Herein we report a means that has been developed to prepare smart polymeric microgels consisting of thermosensitive cores with pH-sensitive shells. The microgels were obtained directly from seed polymerization of N-isopropylacrylamide in supercritical carbon dioxide (scCO2). The effects of initial amounts of cross-linker, and Poly (dimethylsiloxane)-graft- polyacrylates (PDMS-g-PAA) on the yield and morphology of the resulting polymer were investigated. PDMS-g-PAA and crosslinker worked effectively as surfactant. PNIPA/PDMS-g-PAA particles with diameters in 50 nm were produced in scCO 2, in high yield and in short reaction times.
