Microphase separation is normally observed in block copolymer films when the equilibrium of a polymer film is broken by external circumstances such as pressure or temperature. Block copolymer film is consist of two or more homopolymers linked with covalent bond. As the annealing condition is controlled, the morphology of block copolymer film is changed to ordered arrangement. The block copolymer films have various nano structure like cubic, hexagonal, bicontinuous and lamellar depending on the volume fraction of each homopolymer. In this study, Atomic Force Microscopy (AFM) was used to obtain the information of nano-structured diblock copolymers and blend homopolymers. The AFM results from various modes provided the information about the surface morphology, physical properties and microphase separated structure of the copolymer films before and after annealing treatment.
