Surface patterning via wetting and drying
When deformation occurs and under the right stimulus, the Shape Memory Hybrid (SMH) recovers back to its original shape. This occurrence is known as Shape Memory Effect. This report focuses on the control of surface patterning such as wrinkles by shape memory effects of Hydrogel/Polyethylene glycol...

When deformation occurs and under the right stimulus, the Shape Memory Hybrid (SMH) recovers back to its original shape. This occurrence is known as Shape Memory Effect. This report focuses on the control of surface patterning such as wrinkles by shape memory effects of Hydrogel/Polyethylene glycol (HG/PEG) hybrid via wetting/drying. A variety of hydrogels and different weight percentages of PEG were used during this project.
