Key Points

  • This research aims to develop a method for inducing anisotropic swelling in hydrogels.
  • Induced anisotropic swelling in pH-responsive hydrogels.
  • Utilized polarity differences between zwitterionic and non-zwitterionic monomers.
  • Generated chemical gradients to direct shape changes.
  • Demonstrated controlled deformations in response to pH changes.
  • Successful formation of chemical gradients enabled targeted design of hydrogel properties.

Abstract

We present a method to induce anisotropic swelling in pH-responsive hydrogels through polarity differences between zwitterionic and non-zwitterionic monomers. This results in chemical gradients that enable controlled deformations upon pH change.
