Polyurethane/montmorillonite nano-composites were synthesized,and then used for fiber *** viscosity of the spinning solutions,dispersion of montmorillonite in cast films and drawn fibers,as well as the mechanical properties of polyurethane/montmorillonite fibers were *** results indicated that the viscosities of spinning solutions containing montmorillonite were lower than that of the pure polyurethane solution,and the viscosity of spinning solutions increased after standing 24 h at room *** images showed that montmorillonite particles were dispersed at the scale from nanometer to micrometer in fiber *** with pure PU fibers,the mechanical properties of polyurethane/montmorillonite composite fibers were not improved except that the elongation at break was slightly increased.
Since the earlier report on using the phosphorescent material in organic light-emitting diodes (OLEDs) can achieved high external quantum efficiency by Forrest et al., many transition metal complexes,

Theoretically, europium complexes are the most suitable luminescent materials for red electroluminescent (EL) devices because they can emit highly monochromatic red light and offer 100% emission quant
