Abstract
The present invention provides a shape memory material with a chelating system. The shape memory material with the chelating system comprises polyurethane and a metal complex in a mass ratio of 100:(1-10), and the polyurethane is obtained by reaction of the following components by weight percent: 9.0-10.0% of methylenediphenyl diisocyanate, 0-2.0% of chain extender, 0-3.0% of chelating agent, and 87.0-88.0% of polycaprolactone diol. The present invention provides a novel shape memory material polyurethane-manganese dioxide (SMPU-MnO) chelating material. Collaboration of its mechanical strength, shape memory performance and Mnresponsive release is achieved through the chelating system, and shape recovery is performed by means of the photothermal effect of manganese dioxide under remote control of near-infrared light to achieve self-fixed filling of an irregular bone defect part and responsively release manganese ions, so as to achieve a bone repair biological function.
