Four hybrid materials of RE2O3-TDI-CS (TDI=toluene 2,4-diisocyanate, CS=chitosan, RE=Nd, Eu, La, Sc) were prepared by the method of graft. The materials were characterized by infrared spectroscopy, thermogravimetric and scanning electron microscopy, and results showed that the CS was grafted on the surface of rare earth nano-oxides which was modified by TDI. The results of the experiment of anticoagulant and recalcification time showed that the materials have better anticoagulant action than that of RE2O3.

Key words: chitosan (CS), rare earth nano-oxide, hybrid material, anticoagulant, recalcification
