Strong, Reversible, Heat‐Activated Adhesion from Liquid Crystal Polymer Networks (Adv. Mater. Interfaces 36/2024)

Liquid Crystal Elastomers In article 2400488, Mohand O. Saed and co-workers develop reusable liquid crystal adhesives with controlled transition temperatures (Tg and Ti). These adhesives show low tackiness in the glassy and isotropic phases, becoming activated between Tg and Ti. They are reusable across multiple heating and cooling cycles, resistant to contamination, and offer lap shear and peel strengths comparable to traditional pressure-sensitive adhesives (PSAs).
