Abstract
The invention discloses a preparation method of a high polymer product provided with a multi-scale foam structure. The method includes that raw materials are molded to be samples, then the samples are placed in an autoclave, supercritical fluid is introduced into the autoclave, pressure is maintained, or the raw materials and the supercritical fluid are simultaneously added into a molding device, the synergistic effect of temperature rise and pressure relief is utilized to foam high polymer materials, and different foaming performances of the high polymer materials are combined to manufacture the high polymer product provided with the multi-scale foam structure. Compared with a common foaming method, the preparation method of the high polymer product provided with the multi-scale foam structure can improve connectivity of the manufactured product which can be used for aspects such as tissue engineering, super-hydrophobic, filtering and the like. Besides, the method is less in process, capable of achieving batch production, and easy to promote in industrial production.
