摘要

本實驗以原子轉移自由基聚合法 (Atom Transfer Radical Polymerization，ATRP)合成聚偏二氟乙烯(Polyvinylidene fluoride, PVDF)與甲基丙烯酸甲酯(Methyl methacrylate , PMMA)之接枝共聚物(PVDF-g-PMMA)。利用紫外光-可見光吸收光譜儀(UV-Visible)，探討不同變因對於觸媒系統的影響。合成後的產物以傅利葉紅外線光譜儀(FTIR)與核磁共振光譜儀(NMR)證明接枝共聚物的合成。將此接枝共聚物混掺PMMA後利用乾式成膜法製備薄膜，以熱重損失分析儀(TGA)及微分掃瞄熱分析儀(DSC)測量接枝混掺膜之熱性質的變化。進一步以索式萃取法製備多孔性薄膜後，以廣角X光繞射儀(XRD)、小角度X光散射儀(SAXS)與場發射電子顯微鏡(FESEM)探討薄膜的結構與物性。

The present research utilized PVDF and PMMA to synthesize graft copolymer by the method of atom transfer radical polymerization. Utilize ultraviolet visible spectrocomparator (UV-Visible) to characterize catalyst. The chemical structure and composition of graft copolymers was confirmed by FT-IR and NMR. The physical properties of graft copolymer were studied by using TGA, DSC, XRD, SAXS, FE-SEM.
