Abstract

The phenomenon of surface instabilities is usually observed on swelling hydrogels in experiments. The instabilities are owing to small surface imperfections when hydrogels sustain large deformations caused by swelling under certain confinement. This research provides a fundamental framework of instability analysis for three-dimensional perturbed surface patterns on the hydrogel layers under biaxial stretches. The dependences of the critical swelling ratio on the selection of the gel and solvent system are discussed for the case of equal-biaxial confinement using instability maps.
