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

Two EE azido-bridged coordination polymers (M(L)(N3)2, M = Co 1, Ni 2) were synthesized and characterized structurally and magnetically. 1 is a 1D Co-N3- chain presenting spin canting. 2 is a 2D (4,4)

Azide ion can link more than one metal ion in a variety of modes and mediate different types of magnetic coupling. Recently we reported a single End-to-End azide-bridged nickel (II) chain, which shows

Two new 3D NaCl type frameworks of [M(pyrazine)2NO2]ClO4 (M=Co, Cu) consist of (4, 4) sheets of M-pyrazine bridged by μ1,3-nitrito bridges, representing the first examples of a nitrite ion in μ1,3-bri
