The present invention relates to a porous NiTi/gel composite material, functional alloy and application. The invention first provides a porous NiTi/gel composite material and a preparation method thereof. The material is composed of bicontinuous porous NiTi and a gel material filled in the pores of the porous NiTi. Re metal melt assists NiTi alloy to remove Ni element, and after pickling, porous NiTi is obtained, and then porous NiTi is immersed in gel preparation solution for polymerization reaction to obtain porous NiTi/gel composite material. Further, the present invention also provides a functional alloy comprising the above-mentioned porous NiTi/gel composite material. By combining the bicontinuous porous NiTi with the gel material, the invention endows the common material with new functions, has good performance and simple preparation method, and can be widely used in the fields of biomedicine and aerospace. |
