Micelle?crosslinked hydrogels with stretchable, self?healing, and selectively adhesive properties: Random copolymers work as dynamic yet self?sorting domains

The design of crosslinking domains is a vital factor to create functional hydrogels with controlled physical, mechanical, and adhesive properties. This paper demonstrates versatile synthetic systems micelle-crosslinked highly stretchable, self-healing, selectively For this, methacrylate-bearing random copolymer micelles are designed as physical covalent crosslink via the self-assembly amphiphilic copolymers carrying hydrophilic poly(ethylene glycol) (PEG), hydrophobic butyl or dodecyl groups, methacrylate-terminal PEG in water. size, aggregation number, pendant methacrylate number by composition degree polymerization. Hydrogels efficiently obtained from free radical polymerization monomers such acrylate acrylamide presence micelle crosslinkers Owing dynamic yet selective chain exchange properties domains, stretchable up over 1000% show self-healing promoted upon heating due fast whereas consisting different alkyl groups never because their self-sorting
