摘　　要：通过热致相分离法结合双扩散法制备了聚碳酸丁二醇酯(PBC)多孔膜,并将之与聚己内酯(PCL)多孔膜进行力学性能和接触角的比较。发现PBC的接触角小于PCL多孔膜的接触角,但其力学性能不及后者。通过不同分子量的聚乙二醇(PEO)对PBC多孔膜进行改性,其亲水性进一步提高,发现分子量为2.0×105的PEO改性的多孔膜亲水性提高较大,该组膜材料降解速率与亲水性具有正相关性。Poly（butylene carbonate） （PBC） porous membrane was prepared by thermally induced phase separauon （TIPS） combined with double diffusion process. PBC porous membrane was compared with polycaprolactone（PCL） poroUs membrane. It is found that PBC porous membrane has a better hydrophily performance but weaker mechanical properties. Then two kinds of polyoxyethylene （PEO） were added to improve the hydrophility of PBC porous membrane- PEO with molecular weight of 2.0 × 10^5 gave kind 6f PEO also had a faster degradation speed. a better hydrophility, and the membrane modified by this
