Abstract

Self-healing polymers consist of a healing agent that is stored in microcapsules and released wherever crack damage occurs in the matrix. The healing agent flows into the cracks and is polymerized in place, effectively sealing the damage and allowing the material to recover structural integrity. Repair of damage is accomplished automatically and without human intervention, improving performance and service-life of the materials. The development of multifunctional composite materials would alleviate longstanding problems in composite structures associated with multiple types of damage mechanisms such as mechanical/thermal fatigue, microcracking, and debonding. This presentation will focus on several new healing agents such as nontoxic solvents (e.g. healing efficiencies of ca. 100% based on recovery of fracture toughness) along with a brief description of potential applications such as self-sealing composites and epoxy adhesives.
