Encapsulant-containing polymer capsules and fibers and composites including same

Abstract

Systems and methods for preparing encapsulant-containing polymer capsules and fibers, as well as the encapsulant-containing polymer capsules and fibers and composites including the same are described. In one example, forming a plurality of encapsulant-containing polymer capsules includes preparing a mixture comprising a polymer, a solvent, an encapsulant, and a polymer that is soluble in the solvent, and removing some of the solvent from the mixture to yield the plurality of polymer capsules. Each polymer capsule include a shell formed of the polymer and contains the encapsulant. In another example, forming a plurality of polymer fibers containing an encapsulant includes providing the mixture to an electrospin apparatus and electrospinning the mixture to yield the plurality polymer fibers, where each polymer fiber defines a hollow core that contains the encapsulant.
