摘要
Cation-πinteraction is considered one of the strongest noncovalent interactions in aqueous solutions,which endows natural biomolecules(e.g.,proteins)with robust wet adhesion and cohesion in humid/underwater environments.However,it remains a challenge to construct synthetic functional materials(e.g.,self-healing hydrogels)by adopting the cation-πinteractions rationally.Herein,we present a facile and novel strategy to fabricate injectable self-healing synthetic hydrogel from self-assembly of a thermoresponsive ABA triblock copolymer via cation-πinteractions.
