We show that tapping‐mode atomic force microscopy provides real‐space and time‐resolved observations of morphology and pattern formation resulting from crystallisation of annealed thin films of polyethelenoxide or microphase‐separated low‐molecular‐weight hydrogenated poly(butadiene‐ b ‐ethyleneoxide) diblock copolymers. Differences in viscoelastic properties allow distinguishing crystalline and molten (amorphous) areas with a nanometer resolution.
