Abstract: |
The preparation method of porous support for repairing tissue and organ by using phase-separation particle filtering-out method includes the following steps: firstly, preparing biologically compatible polymer solution, adding pore-forming agent into the polymer solution, uniformly stirring and pouring it into a mould and quenching, opening the mould, drying, then soaking the freeze-dried product in deionized water, and finally vacuum drying so as to obtain the invented porous support with high porosity, good biological compability, and bio-degradable property. |
