Seeded Reaction Waves in Composites: Fast Structure Transforming Materials that Respond to Energetic Stimuli

Abstract

Damage in polymer and composite materials is often rapid and catastrophic. Preventing damage requires a new class of material that can autonomically respond to imminent damage by rapidly changing its physical properties. Herein we report several mechanisms by which autonomic material self-protection may be realized. The incorporation of encapsulated super cooled fluids into a polymer matrix allows for rapid changes in mechanical properties. Frontal polymerization within a microvascular network rapidly forms an endoskeletal structure within a flexible rubber, stiffening it up to 18x. Polymer seed particles have also been developed towards enabling a seeded frontal polymerization. Mechanochemical activity at interface
