Comparison of miscibility in poly(N-vinylcarbazole)/polystyrene and polyoxyethylene blends by excimer fluorescence

Polymer Bulletin Aims and scope Submit manuscript

Summary

It is for the first time found that poly(N-vinylcarbazole)(PVCz)/polystyrene (PS) blends have lower miscibility on molecular level than that of PVCz/polyoxyethylene (PEO) blends. This is obtained from excimer fluorescence properties of PVCz in PVCz (9.1–100%)/PS and PVCz (9.6–100%)/PEO blends. Schematic diagrams of phase-separated structure of the PVCz blends are proposed consistent with emission properties and phase-contrast microscopic images.
