Temperature dependence of d-spacing and Transition behavior of PS-b-PMMA/PS homopolymer |
| 초록 |
In this study, we investigated the temperature dependence of d-spacing and transition behavior of polystyrene-b-poly(methyl methacrylate) (PS-b-PMMA)/PS homopolymers using small-angle x-ray scattering (SAXS) analysis, where the various molecular weight (or chain length) of PS homopolymer. The d-spacing and order-to-disorder transition (ODT) by addition of PS homopolymers were significantly influenced by the PS molecular weight. This variation can be attributed to a competing interaction between the thermal swelling effects of the microdomains with homopolymers and the decrease in the chain stretching between the two block components. |
