NOVELTY - Shape memory porous material shaped at body temperature/room temperature, comprises10-90 pts.wt. polymer material, 10-90 pts.wt. transition phase material, and 0-80 pts.wt. additive component material composition; its porosity is 5 to 95%; it can be shaped at 10-45degreesC after preheating, and can return to its original shape after reheating to a certain temperature; its elastic modulus in the range of 0-45degreesC, the amount is 0.01 MPa -10 GPa, the shape fixation rate is 30 to 100%, and the shape recovery rate is 50 to 100%; its porosity is obtained by physical or chemical foaming after blending the polymer material and the transition phase material, or obtained by soaking the foamed polymer material in a solvent in which the phase transition material is dissolved and then removing the solvent. USE - Shape memory porous material shaped at body temperature/room temperature. ADVANTAGE - The material is comfort and lightness, porous, breathable, lightweight, has high compressibility and good air permeability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for method for preparing a shape memory porous material shaped at body temperature/room temperature which involves: a blending foaming method is adopted, that is, the corresponding pts.wt. the polymer material, the phase transition material and the added, component materials are fully mixed, a shape memory porous material that can be shaped at body temperature/room temperature is obtained by physical or chemical foaming; the physical foaming method is to dissolve gas or liquid in the polymer material, and then expand or expand it; gasification foaming; the chemical foaming method is that the gas generated by the thermal decomposition of the added chemical foaming agent or the chemical reaction between the raw material components makes the polymer material fill the cells.
