摘要

采用溶剂铸造颗粒浸出法,在1,1,1,3,3,3-六氟-2-丙醇(HFIP)、二氯甲烷(DCM)和氯仿(CF)三种不同溶剂中,以NaCl为孔隙剂制备了聚乳酸多孔支架。采用扫描电镜(SEM)、傅里叶变换红外光谱(FTIR)对PLA支架的形貌、结构和热行为进行了表征;热重分析(TGA)和差示扫描量热法(DSC)。进一步对制备的多孔支架进行了孔隙率测定、吸溶剂性能和不同温度下的吸水性能表征。与PLA/ HFIP支架(75%)相比,PLA/ CF支架具有更高的孔隙率(93%)和增强的吸水能力(220%)。与PLA/ HFIP和PLA/ CF支架相比,PLA/ DCM支架表现出更高的热稳定性。

Effect of Different Solvents in Solvent Casting of Porous caffolds in Biomedical and Tissue Engineering Applications
In the present investigation, PLA porous scaffolds was fabricated using NaCl as porogen in three different solvents i.e. 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP), dichloromethane (DCM) and chloroform (CF) respectively, by solvent casting particulate leaching method. The morphology, structure and thermal behaviour of the PLA scaffolds for porosity measurement were evaluated using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR); thermo gravimetric analysis (TGA) and differential scanning calorimetry (DSC). The developed porous scaffolds were further characterized for porosity measurement, solvent uptake property and water absorption capacity at different temperatures. PLA/ CF scaffold depicted higher porosity factor (93%) along with enhanced water uptake capacity (220%) as against PLA/ HFIP scaffold (75%). However PLA/ DCM scaffolds illustrated more thermal stability as compared with PLA/ HFIP and PLA/ CF scaffolds.
