Solventless Polymerization at the Gas–Solid Interface to Form Polymeric Thin Films

Polymeric thin films have been prepared by solventless processes that are particularly suitable for building block copolymers into multilayer films (see Figure for an optical image of a two-layer film, scale bar = 50 μm). Using this method, the detrimental effects that a solvent may sometimes have when preparing a film can be avoided.
