本研究利用4,4’-oxydianiline（ODA），bisphenol A（BPA），paraformaldehyde（PF）在乙醇與甲苯之混合溶劑下合成主鏈型polybenzoxazine （PBz），並以紅外光譜儀(FTIR)鑑定其化學結構，以凝膠滲透層析儀(GPC)分析其數目平均分子量以及分子量分布指數，分別為5985 g /mol和4.37。以及使用微差掃描卡計(DSC)和熱重損失分析儀(TGA)測定其熱性質，證實PBz為一熱可交聯高分子。PBz之多孔膜以蒸汽誘導相分離法(VIPS)為之，使用PBz 20 wt%之NMP溶液，於潔淨玻璃板上刮膜後放入密封之玻璃腔內並通入沸水產生之水蒸氣，根據通水蒸氣之時間不同製備出一系列PBz薄膜，乾燥並經熱交聯程序後製得成品。以FTIR鑑定交聯前後薄膜之化學結構，可驗證其交聯反應以及反應機制。以TGA與DSC測定交聯後薄膜之熱性能，結果顯示交聯後之PBz具有耐高溫之特點，用SEM鑑定薄膜之孔洞結構，證明其多孔性，其中在水蒸氣中放置10分鐘之薄膜其孔洞大小為3.42±0.30 μm，孔隙率為18.6±0.8 %。用浸泡多種有機溶劑之方法可測得薄膜之Gel fraction為接近100 %，表明該PBz膜具有耐有機溶劑性。用拉力機可鑑定薄膜之力學性能，表明該薄膜有優越的力學性能。最後鑑定該薄膜之分離性能，結果表明該薄膜能夠有效分離有機溶劑中之水分及顆粒雜質，並且轉變其表面性能後能使該薄膜由親有機溶劑轉變為親水，能有效分離水溶液中之有機溶劑雜質。

In this study, we have synthesized polybenzoxazine(PBz) in the mix solvent of toluene and ethanol using 4,4’-oxydianiline(ODA), bisphenol A (BPA), paraformaldehyde(PF). After that, we use FTIR to characterize the chemical structure of PBz which proves PBz is successfully prepared. Then, we can get the molecular weight and distribution of prepared PBz are 5985 g/mol and 4.37 respectively via GPC. And then, we use vapor-induced phase separation method(VIPS) to fabricate membranes. We can get a series of membranes kept in the vapor for different period of time. After that, we put the membrane into the oven to be crosslinked. After that, some basic features of membranes are available by some characterizations. The pore size of the membrane kept in vapor for 10 minutes is 3.42±0.3 μm, porosity is 18.6±0.8%. Using FTIR to characterize the chemical structure of crosslinked PBz and compared with the initial PBz, we are able to understand the mechanism of PBz crosslink process. The high temperature resistance is comfirmed by TGA and DSC. Besides, we use SEM to characterize the membrane structure and demonstrate the porous structure of the prepared membrane. Gel faction, which is nearly 100%, confirms the good anti organic solvent corrosion property of PBz membrane. And also, the good mechanical strength of membrane is confirmed by tensile test machine. Most importantly, we test the separation ability of the membrane. We use karl fischer titration machine to detect the water content in emulsion and used ultraviolet-visible spectrometer to detect the toluene content in emulsion. The size distribution of particles is detected by Malven zetasizer. The results of separation test show that this membrane can remove particles and water in organic solvent successfully. Besides, after immersed into NaOH, the surface property of the membrane will be hydrophilic and it can remove organic solvent in waste water with high separation efficiency.
