Controlled in situ formation of polyacrylamide hydrogel
2. Experimental 2.1. Materials. All reagents and solvents were purchased from Sigma–Aldrich or Fisher Scientific and used as received. Mylar ® PET films with a thickness of around 0.1 mm were purchased from a local bookstore. PET films were cut by 2 × 2 cm 2 and washed with acetone and water to remove any dirt on the surface and kept in desiccator for future use.

Strengthening Alginate/Polyacrylamide Hydrogels Using
We successfully synthesized a family of alginate/polyacrylamide hydrogels using various multivalent cations. These hydrogels exhibit exceptional mechanical properties. In particular, we discovered that the hydrogels cross-linked by trivalent cations are much stronger than those cross-linked by divalent cations. We demonstrate stretchability and toughness of the hydrogels by inflating a
