发帖数: 589 | 1 The clarity of high-concentration polymer solutions (e.g., > 10 wt.%
polymer) can distinguish between block copolymer structures and incompatible
polymer blends. Since block copolymers constitute a single chemical species,
they produce clear single-phase solutions. On the other hand, incompatible
homopolymer blends result in cloudy solutions that eventually separate into
two liquid layers due to well-known thermodynamic immiscibility phenomena. |
