Crosslinked polymer networks with self-healing abilities were prepared by the combination of two different fluorinated copolymers through dynamic nitrogen-coordinated boronic ester linkages (NCBE). The two fluorinated copolymers, one having pendant glycidyl group and the other one with pendant boronic acid groups, were synthesized by radical solution polymerizations, respectively. And, the glycidyl containing copolymer was further modified to have an amine and two hydroxyl groups. Because of reversibility of the dynamic NCBE linkages, the crosslinked fluorinated copolymer network exhibited excellent autonomous self-healing ability at mild condition. Further, these materials features good optical transmittance (90%) in full visible light region and self-cleaning effects. All of these properties were stably maintained under harsh environments, which render these materials to be used for various protective coating applications.
