Viscoelastic polymer adhesion is everywhere in the industry —from aerospace and electronics to packaging— and it also drives advances in cutting-edge technologies such as soft biomimetic robotics and tissue engineering. As a major topic in soft matter physics, it sits at the intersection of mechanics, rheology, and interfacial science. This M2 internship and PhD project offers an outstanding opportunity to explore the fundamental mechanisms behind the detachment of microscopic fibrils formed during the peeling of viscoelastic adhesives. Ultimately, the goal is to establish and validate a model capable of quantitatively predicting the adhesion strength of adhesive tapes from the material intrinsic properties.
