The invention discloses a red light responsive shape memory polymer material and a preparation method thereof, belonging to the technical field of functional materials. The polymer material provided by the invention is obtained by cross-linking reactive group-containing micelles, wrapping porphyrin, into a film; the polymer material is prepared from the following raw materials in parts by weight:20-40 parts of allyl monomer containing hydrophobic groups, 1-5 parts of allyl monomer containing hydrophilic groups, 1-5 parts of allyl monomer containing reactive groups, 2-5 parts of organic solvent, 0.5-1 part of radical initiator, 1-5 parts of cross-linking agent and 0.0005-0.005 part of porphyrin. The red light responsive shape memory polymer material is endowed with a red light responsive shape memory function invention by wrapping the porphyrin having a photothermal conversion function in the micelles, avoids the traditional contact type triggering response, and can realize the manipulation of the material shape memory behavior remotely; furthermore, as an organic compound inherent in a living body, the porphyrin does not cause harmful side effects to the living body; the red lightdoes not damage the skin when penetrating the living body, and the energy loss is less; therefore, the red light responsive shape memory polymer material is expected to be applied to the photothermaltreatment in the living body.
