Scanning Electron Microscopy (SEM) images of Pathway-primed Layered Block Copolymer Thin Films

Scanning electron microscopy (SEM) images (top-view and perspective view) of a variety of block copolymer (BCP) thin films. The films were formed by layering different BCP types and thermally annealing (at various temperatures and annealing times). The SEM images provide information about the nanostructure that forms as a result of the particular preparation/annealing history.
