Abstract

The solvent-based self-healing approach used in thermosets1, 2 has been extended to thermoplastic materials in which common organic solvents are used as compartmentalized liquid healing agents. Robust, solvent-filled poly(urea-formaldehyde) microcapsules are compounded into a thermoplastic poly(methyl methacrylate) matrix and then injection molded into compression test specimens. MicroCT (computed tomography) imaging is used to determine capsule survival rate after each processing step. Mechanical testing is performed on the double cleavage drilled compression3 specimens. Upon crack damage, solvent is released from the embedded microcapsules, which leads to polymer chain entanglement across the crack plane to restore the virgin fracture toughness to the material.
