我們製作聚偏二氟乙烯（PVDF）在水-磷酸三乙酯（TEP）溶液在常溫25℃中之相圖。並以浸漬-沉澱法來製備多孔型薄膜。薄膜的結構乃以電子顯微鏡加以觀察。結果顯示依製膜條件變化，薄膜可形成非對稱或對稱型結構。 Phase diagram of PVDF in water-TEP solutions was determined at 25℃.On the basis of the phase diagram, porous PVDF membranes were preparedby the immersion precipitation method. The porous structures of theformed membranes were observed in SEM. It was found that, dependingupon the preparation conditions, the membranes could assume eitherasymmetric or symmetric structures.
