Abstract:
A novel approach to prepare surfactant-free poly(methacrylic acid)(PMAA) nanohydrogels using hydroxypropyl cellulose as template in water solution was demonstrated. pH and temperaturesensitive coreshell nanogels using PMAA nanohydrogels as template were synthesized. The sizes of PMAAPNIPA nanohydrogels were in the range of 338.8-407.9 nm, and decreased with the increasing of the content of crosslinking agent. The nanohydrogel showed good pH-temperature responsive behaviors. The nanohydrogel synthesized with soap-|free emulsion polymerization will be applied in numerous fields.
