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.
- core-shell microgels,
- composite polyampholyte hydrogels,
- high mechanical strength,
- pH sensitivity
