Abstract: Nanoscale confinement and surface interactions offer powerful means of controlling polymer behavior. This dissertation investigates how these factors govern polymer replacement, molecular sorption, and material stability using densely packed silica nanoparticles as a tunable experimental platform. Sequential infiltration experiments reveal selective, directional replacement of one polymer by another, governed by relative surface affinity and […]
