CAS Lanzhou Institute of Chemical physics develops double-sided adhesives that reversibly sticks to surfaces under water

The material is inspired by Gecko bionics and based on an inorganic membrane to which hydrogel nanofibers are added on both sides. The material exhibits ultra-high friction and adhesion in an acidic liquid (pH 2), and switches rapidly to a state of ultra-low friction and stickiness in a basic solution (pH 12). Additionally, the two sides of the material can stick and slide independently of each other.
