Snail epiphragm leads to new adhesive

 Snail epiphragm
Inspired by snail mu­cus, This research was done by  scientists at Lehigh University, state University of Pennsyl­vania and the KIST (Korea Institute of Science and Technology) created an adhesive more similar to superglue that they identify as “intrinsically re­versible.”  Achieving both reversibility and strong adhesion is more challenging. Ac­cording to Anand Jagota who is one of the leading professors of this research, this contains nearly 90% water which is considered pure hydrogels. Furthermore, he explains that adhesives normally fall into 1 of 2 categories: strong but reversible and reusable but weak or irreversible, like superglues.

How they inspired adhesive similarity with snail epiphragm


As per the report, The research team demonstrated that when hy­drated, the softened gel they made conformally adapts to the target sur­face by low-energy deformation, which is then locked upon drying in a manner similar to the action of the epiphragm of snails. A snails epiphragm is a tempo­rary structure created by snails and mollusks. Made of dried mucus, it holds in moisture during periods of inactivity and enables snails to adhere to surfaces such as rocks. The scientists show that reversible, super-strong adhesion can be achieved from a nonstructured ma­terial when the criterion of shape adap­tation is met. According to the research­ers, the new material can be applied to both flat and rough target surfaces.

It is so vital to have such inspiration as the advancement of science and technology should make the world a better place for the living being. This latest scientific research reveals us the true benefit taken by the researches out of wild creatures that we never think of. materialtoday.co will share with you the alerts of the latest researches and keep in touch with us.
