The microstructure of block copolymer‐reinforced interfaces of homopolymers has been studied by frictional force microscopy (FFM). The FFM micrograph in the Figure shows details, e.g., lamellar branching, of a poly(styrene)/poly(2‐vinylpyridine) (PS/PVP) homopolymer interface reinforced with a PVP–PS–PVP triblock copolymer. An explanation for the need to “develop” the FFM image is proposed and the advantages of FFM over TEM are discussed.
