OBJECTIVE To prepare N-isopropylacrylamide( NIPAM) based thermosensitive ionic nanogels for drug loading by electrostatic adsorption. METHODS The emulsion polymerization( EP),seed emulsion polymerization( SEP) and soap-free emulsion polymerization( SFEP) were used to prepare nanogels by copolymerization of NIPAM with acrylic acid( AAc) or β-sulfatoethyl methacrylate( SEMA). The morphology,size,temperature-sensitivity and co-monomer content of obtained nanogels were characterized by TEM,PCS and potentiometri...
