| titleOfInvention | A preparation method of foam material applied to bone trauma fixation |
| abstract | The invention discloses a preparation method for bone trauma fixation foaming material. Supercritical CO2 is used as a foaming agent, and the method of increasing temperature and increasing pressure and lowering temperature and pressure is adopted to make supercritical CO2 in PMMA polymer. Phase transition to prepare foamed materials. First, the PMMA powder and the initiator BPO are uniformly mixed with a certain mass ratio to obtain the pre-polymerized precursor solid phase of the bone trauma fixation foaming material; The phenol is mixed uniformly at a certain mass ratio to obtain the prepolymerized precursor liquid phase of the bone trauma fixation foam material ; Material. The foaming material prepared by the invention has a high foaming ratio, has interconnected micron-sized pores inside, has good air permeability, good biological performance, has certain mechanical strength, and can play a good role in fixing and protecting bone trauma. |
