Change of Miscibility Window of PC and PMMA by adding Multiwall Carbon Nanotubes |
| 초록 |
The blends of polycarbonate (PC) and poly(methyl methacrylate) (PMMA) are well known to be miscible around room temperature and be partially miscible at the temperature higher than a critical point. This behavior is well known as a lower critical solution temperature (LCST) behavior. We prepared transparent PC-PMMA films and obtained LCST curve. We calculate binodal and spinodal phase separation curves by Flory-Huggins theory. The cloud points are well consistent with the spinodal phase separation curve calculated by F-H theory as reported elsewhere. We demonstrated the phase behavior of PC-PMMA blends are changed by adding a small amount of multiwall carbon nanotube. Model calculations are also performed to analysis the change of phase behavior. |
