A new strategy to fabricate composite thin films with tunable micro- and nanostructures via self-assembly of block copolymers†
Abstract
A new and facile strategy to fabricate composite thin films with tunable morphologies via self-assembly of block copolymer molecules at the air/liquid interface is first reported. The morphologies (parallel nanowires and foams) of these freestanding thin films can be tuned by varying the molecular structure or other experimental conditions.
