Abstract
Self-healing compositions, method of preparation and uses thereof are disclosed. In an example, a self-healing composition includes a first microcapsule and a second microcapsule. The first microcapsule includes a first polydimethylsiloxane resin, a first silicone fluid, a first functionalized alkoxysilane, and a catalyst capable of catalyzing hydrosilylation reactions, and the second microcapsule includes a second polydimethylsiloxane resin, a second silicone fluid, a second functionalized alkoxysilane, and a hydrogen-terminated dimethyl siloxane resin. In this way, the self-healing composition releases and mixes contents of the first microcapsule and the second microcapsule upon the rupture thereof, imparting a passively initiated repair process to the self-healing composition.
