Polymerization process of hydrogel microspheres on videoAqueous free-radical precipitation polymeriz
Polymerization process of hydrogel microspheres on videoAqueous free-radical precipitation polymerization is one of the most useful methods to prepare uniformly sized hydrogel microspheres (microgels), and an understanding of the polymerization mechanism is crucial to control the structure or physicochemical properties of microgels. However, the details of the mechanism of precipitation polymerization remain unclear.Thus, first author Yuichiro Nishizawa, Prof. Daisuke Suzuki of the Graduate School of Textile Science & Technology, Shinshu University and Prof. Takayuki Uchihashi of Nagoya University set out to clarify the formation mechanism of microgels during precipitation polymerization by evaluating structural evolution and thermoresponsiveness of developing microgels during polymerization and by visualization of polymerization directly.Through the direct visualization of the microgels with different polymerization times, it was clarified that some inhomogeneous, non-thermoresponsive nanostructures existed in the thermoresponsive microgels formed in the initial stages of precipitation polymerization.Read more. -- source link
