[摘要]：The disorder to order transition of comb copolymer A(m+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 in 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 A(m+1)B(m) 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 in and shorter side chain. |
