Experimental study demonstrates the synthesis of oxygen-tolerant dynamic covalent polymer micelles at room temperature, highlighting potential applications in robust self-healing nanomaterials.
We report the preparation of amphiphilic block copolymer micelles with dynamic covalent bonds as autonomously exchangeable crosslinkers with high tolerance against oxygen. Diarylbibenzofuranone (DABBF) was employed as a crosslinker owing to its durability to oxygen and autonomous exchangeability at ambient temperature. It was confirmed that the amphiphilic block copolymer containing the DABBF unit has the capability to form micelles and can form a crosslinking with an exchangeable structure in the presence of oxygen.
