Shape Memory Assisted Self-Healing Coating
In this communication, we report the preparation and characterization of new shape memory assisted selfhealing (SMASH) coatings. The coatings feature a phaseseparated morphology with electrospun thermoplastic poly(εcaprolactone) (PCL) fibers randomly distributed in a shape memory epoxy matrix. Mechanical damage to the coating can be self-healed via heating, which simultaneously triggers two eve...
متن کاملRapid self-healing hydrogels.
Synthetic materials that are capable of autonomous healing upon damage are being developed at a rapid pace because of their many potential applications. Despite these advancements, achieving self-healing in permanently cross-linked hydrogels has remained elusive because of the presence of water and irreversible cross-links. Here, we demonstrate that permanently cross-linked hydrogels can be eng...
متن کاملExtremely Stretchable and Fast Self-Healing Hydrogels.
Dynamic crosslinking of extremely stretchable hydrogels with rapid self-healing ability is described. Using this new strategy, the obtained hydrogels are able to elongate 100 times compared to their initial length and to completely self-heal within 30 s without external energy input.
متن کاملSelf-healing hydrogels containing reversible oxime crosslinks.
Self-healing oxime-functional hydrogels have been developed that undergo a reversible gel-to-sol transition via oxime exchange under acidic conditions. Keto-functional copolymers were prepared by conventional radical polymerization of N,N-dimethylacrylamide (DMA) and diacetone acrylamide (DAA). The resulting water soluble copolymers (P(DMA-stat-DAA)) were chemically crosslinked with difunctiona...
