  2. Aim : to analyze the mechanism, thermadynamic theoretical basis, dynamic mechanism and influencing factors of thermally induced phase separation ( tips ) in order to completely grasp the factors affecting the size, distribution and form of pores, so that the adjusted range of pore can be widened and the preparation of porous membrane can be repeated and controlled. methods : considering from the structural characteristics of tissue engineered materials, the methods of preparing porous membrane using tips technique, the hermadynamic theoretical basis, dynamic mechanism and influencing factors were analyzed, the problems and investigative directions in the future were also analyzed. tips technique is a process of phase separation of polymer homogenous solution under quenching, and it is suitable for diameter and structural form of the micropore materials prepared using tips are closely correlated with the kind and dispensing proportion of polymer attrnuant, polymer concentration and polymer molecular mass, etc. conducted, including determination of polymer - solvent system phase diagram, study of form and appearance of porous membrane of different thickness, study of form and appearance of porous membrane prepared with systems of different x, which is the parameter of polymer - solvent interaction

    目的:分析熱致相分離成膜過程的機理、熱力學理論基礎、動力學機制以及影響因素，以便充分掌握影響孔度大小、分佈、形態的因素，使孔度調控范圍得以拓寬，使多孔膜的制備能重復可控.方法:從組織工程材料結構特點出發，分析熱致相分離聚合物多孔膜的制備方法及該法成膜的熱力學理論基礎、動力學機制以及影響因素.並分析實驗中存在的問題及今後的研究方向.結果:以熱致相分離法可制備聚合物多孔膜.熱致相分離法制備多孔膜是高聚物均相溶液在淬冷條件下發生相分離的過程，它適用於上臨界共溶溫度型聚合物一稀釋劑二元體系.熱致相分離法成膜的過程，可以認為是旋節線機理佔主導地位.熱致相分離法制備的微孔材料，其孔隙率、孔徑大小、結構形態與聚合物稀釋劑的種類、組成配比、聚合物濃度、聚合物分子量等因素密切相關.結論:可採用熱致相分離技術制備多孔膜，通過改變不同的成膜條件可獲得一系列不同孔徑尺寸和孔徑分佈的多孔膜材料.對熱致相分離成膜過程中聚合物-溶劑體系的相圖測定，不同厚度的多孔膜形貌研究，不同x （聚合物-溶劑相互作用參數）體系所制備的多孔膜形貌等需深人研究
