Reversible super inspiration is inspired by snail epiphragm

The researchers proposed a snail epiphragm-inspired adhesion mechanism in which the polymer gel system exhibits glue-like bonding strength (up to 892 N.cm -2), which is also reversible.
adhesives are ubiquitous in everyday life and industrial applications. They usually fall into one of two categories: strong but irreversible (e.g., super glue) or reversible/repeatable but weak (e.g., pressure-sensitive adhesives and biological and bionic surfaces)

to achieve strong adhesion and reversibility has always been a challenge. This task is particularly difficult for hydrogels because their main component is liquid water, which is not usually strongly adhered to any material.
Ultra-strong adhesion strength
Scientists have now proposed a snail epiphragm-inspired adhesion mechanism in which the polymer gel system exhibits glue-like bonding strength (up to 892 N.cm -2), which is also reversible. It is suitable for flat and rough target surfaces. In its hydrated state, the softened gel adapts to the target surface by low-energy deformation, and when the elastic modulus is increased from a few hundred kPa to 2.3GPa, it is locked in a drying, similar to the role of the snail epiphragm.
researchers have also shown that in this system, bonding strength is based on the inherent properties of the material, especially near-surface properties, rather than any near-surface structure, providing reversibility and ease of scalability for practical applications.
