Scientists at the University of Tokyo have created a new glue that is incredibly strong and can stick to non-stick surfaces like Teflon. It's also easy to remove with just a little alcohol.
Scientists in Japan have made a breakthrough discovery - a super strong glue that can stick to even non-stick surfaces! This new glue, called CyclicFP-fmoc, is made of small molecules that work together to create an incredibly strong bond. Unlike traditional glues, this one doesn't use long polymer chains, which makes it flexible and easy to remove.
The researchers tested the adhesive strength of their glue by sticking two non-stick Teflon plates together and trying to pull them apart with a machine. The glue held firm against a tensile stress of 1.3 megapascals - that's incredibly strong! They also showed that the glue can lift and suspend an 8-kilogram weight.
But what makes this glue truly special is that it's easy to remove without leaving any residue. All it takes is a splash of ethanol, which washes it away completely. The researchers even showed that the recovered adhesive could be reused more than 10 times while retaining its performance.
Why It Matters
This new glue has the potential to help manufacturers easily separate components in electronics and other products for recycling, making it an important step towards a sustainable society.
