Abstract Scope |
A common approach to imbue polymers with useful functionality is to add nanoparticles to produce nanocomposites. Despite decades of research, however, it remains a challenge to produce nanocomposites with very high concentrations (> 50 vol%) of nanoparticles using conventional methods. In this talk, I will describe a simple, potentially scalable method to manufacture nanocomposite films with extremely high fractions of nanoparticles. A bilayer of polymer and nanoparticles is heated above the glass transition temperature of the polymer to induce capillary rise infiltration (CaRI) of the polymer into the interstitial voids of the nanoparticle packing, producing a nanocomposite film with an extremely high filler fraction (> 60 vol%). I will describe the impact of nanoconfinement on the dynamics of polymer infiltration and also discuss how the composition of the CaRI nanocomposite affect their structure as well as their optical and mechanical properties. |
