Nature inspired solid-liquid phase amphibious adhesive
Here we report a new class of bio-inspired solid-liquid adhesive, obtained by simple mechanical dispersion of PVDF (polyvinylidene fluorine) (solid spheres) into PDMS (polydimethylsiloxane) (liquid). The adhesive behaviour arises from strong solid-liquid interactions. This is a chemical reaction free adhesive (no curing time) that can be repeatedly used and capable of instantaneously joining large number of diverse materials (metals, ceramic, and polymer) in air and under water. The current work is a significant advance in the development of amphibious multifunctional adhesives and presents potential applications in a range of sealing applications, including medical ones.
