Ordering kinetics in two-dimensional hexagonal pattern of cylinder-forming PS-b-PMMA block copolymer thin films: Dependence on the segregation strength

This paper reports the experimental determination of the growth exponents and activation enthalpies for the ordering process of standing cylinder-forming all-organic polystyrene-block-poly (methyl methacrylate) block copolymer (BCP) thin films as a function of the BCP degree of polymeriz
