Faster than Ever? Hydrogels Bond to Soft and Hard Surfaces (11 of 19)

Caption

The pictures show a peeling test, with a hydrogel (green) instantly tough bonded to a PMMA (Polymethylmethacrylat) substrate. A liner serves as stiff backing. Cracking in the hydrogel occurs perpendicular to the peeling direction. This material relates to a paper that appeared in the June 21, 2017, issue of Science Advances, published by AAAS. The paper, by D. Wirthl at Johannes Kepler University Linz in Linz, Austria, and colleagues was titled, "Instant tough bonding of hydrogels for soft machines and electronics."
