Abstract

Abstract:

The composite polyampholyte hydrogels (CAH) were prepared by inserting core-shell microgel particles into a bulk polyampholyte matrix. CAH gels with uniform and tight network structure have excellent mechanical performance due to the entanglement between microgels and network chains, and exhibit an antipolyelectrolyte effect and pH-sensitivity. And ionic strength drastically affects their swelling behaviors. Meanwhile, CAH gels show rapid shrinking rate and transmittance switch in response to the temperature change as a result of the incorporation of microgel particles.

Key words: core-shell microgels, composite polyampholyte hydrogels, high mechanical strength, pH sensitivity, temperature-sensitive
