Porous Scaffolds Based on Cross‐Linking of Poly(L‐glutamic acid)

Porous scaffolds based on water‐soluble PLGA and CS were prepared. The pores were verified to be alveolate, uniform and continuous. The effects of freezing temperature, freeze‐drying time, solid content and molecular weight of reactants on the pore structure of the scaffolds were studied. The scaffold morphology could be adjusted by changing the freezing temperature and solid content of reacting polymer. Their degradation rate can be adjusted by...
