Phase Behavior Tuning of Polystyrene-block-Poly(n-alkyl methacrylate) Copolymers Introducing Random Copolymer as a One Block |
| 초록 |
The phase behavior of polystyrene-block-poly(n-butyl-random-n-hexyl) methacrylate (PS-b-Pn(B-r-H)MA) copolymers and polystyrene-block-poly(n-octyl-random-methyl) methacrylate (PS-b-Pn(O-r-M)MA) copolymers were investigated by using small angle X-ray scattering, birefringence and rheometry. When the total molecular weight and composition of random copolymers were judiciously controlled, the closed-loop consisting of a lower disorder-to-order transition and an upper order-to-disorder transition was observed. The phase behavior by including a random copolymer as one of the blocks was explained by a compressible mean field approach. We found that these block copolymers also exhibited excellent baroplasticity. |
