英文摘要: A microencapsulation and nanoparticle deposition technique, termed repair-and-go, is employed for inducing mechanical restoration of damaged polymer films. In repair-and-go, polymer-stabilized emulsion droplets, containing surface-functionalized SiO2 nanoparticles, traverse a substrate and deposit their nanoparticle contents selectively into the damaged regions. Surface-oxidized poly(dimethylsiloxane) is employed as the substrate, and dynamic mechanical analysis reveals the enhanced mechanical properties of the film following nanoparticle deposition. Healing efficiency is optimal when using thinner test substrates, repeated deposition cycles, and functional SiO2 nanoparticles that afford access to postdeposition curing.
