    Abstract: 聚偏二氟乙烯(PVDF)為一穩定性極佳之線性高分子,並廣泛的應用於工程材料及生醫材料。在本研究,我們利用原子轉移自由基聚合法(ATRP),合成出不同接枝量的共聚物(PVDF-g-PMMA)。分別將此接枝共聚物與聚甲基丙烯酸甲酯(PMMA)依不同比例以溶液混?後製膜,再以溶液洗去PMMA,使薄膜形成多孔性結構。藉此二高分子不同的混?比例及不同的乾式成膜條件,進而製備出具有奈米孔隙的多孔性薄膜。PVDF-g-PMMA的合成利用FT-IR、DSC、TGA與NMR來分析,並以FESEM觀察多孔性薄膜的結構,在某些情況下,接枝上的PMMA以顆粒的形態分佈在PVDF基材中,多孔性薄膜的孔徑約為數十奈米到數百奈米左右。
