Abstract
The disorder to order transition of comb copolymer Am+1(BC)m is investigated by the self-consistent field theory. The interaction parameters between the three different blocks are considered by varying the composition of the comb triblock copolymer with the side chain number m = 1 and 3. As the side chain number m increases, the Flory–Huggins interaction parameter of disorder to order transition (DOT) increases and the lowest DOT occurs when the volume fractions of blocks A, B, and C are approximately equal. When one component is the minority, the disorder-to-order transition curve is similar to binary Am+1Bm comb copolymer. The influence of the side chain density on phase transition is also discussed. The comb copolymer is more difficult to phase separate with larger side chain number m and shorter side chain.
