Abstract
Systems and methods of providing a self-healing UV-protective polymer coating include a polymer matrix formed by initiating polymerization of a UV-absorbing-matrix precursor and a UV initiator and a self-healing portion disposed within the polymer matrix. The polymer matrix includes a plurality of active sites therein. The self-healing portion includes a self-healing precursor that is flowable and a self-healing initiator. The self-healing initiator is configured to polymerize the self-healing precursor using a cationic ring opening process.
