Innentitelbild: A reversible water‐based electrostatic adhesive (Angew. Chem. 2/2024)

Complementary aqueous emulsions stabilized by oppositely charged polyelectrolytes form films that adhere many plastic and other surfaces well. However, at both high and low pH these films can be detached, creating a reversible adhesive. Such a glue has many possibilities to change how industries recycle end‐of‐life components. The glue can coat surfaces just like a paint, has a long shelf life, and does not degrade in humid environments, as reported by Mark Geoghegan et al. in their Research Article (e202310750).
