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.
To obtain low dimensional cyano-bridged complexes, [Cr(CN)4(L)]- (L = phen or 2,2’-bpy) was used as a building block reacted with a series of schiff base-complexes of Mn(III). Two chain complexes were
