Self-healing and photoluminescent carboxymethyl cellulose-based hydrogels

Nature resource-derived hydrogels with the properties of both self-healing and photoluminescence are urgent needed to develop. Herein, we demonstrate that carboxymethyl cellulose (CMC)-based hydrogels can be engineered to exhibit the integrate capabilities of self-healing, photoluminescence and stretchability by a facile, green and economic approach. The CMC-based hydrogels present blue-green color under ultraviolet light, and self-heal in...
