本實驗是經由兩種相轉移法-乾式相轉移和乾濕式相轉移法製備PMMA/蒙脫土 (montmorillonite,MMT) 之複合薄膜,希望能製備出帶有離子交換以及擁有吸附能力的薄膜。以ATR-FTIR分析高分子之組成;並以TGA觀察薄膜裡的蒙脫土是否有損失。本研究並以SEM觀察薄膜的接觸空氣面、接觸玻璃面以及截面是否為多孔性薄膜;接觸角分析儀以及含水率測量高分子薄膜之親疏水性。
在PMMA/Na+-MMT複合薄膜離子交換容量的部份,當Na+-MMT/PMMA重量比值增加時,薄膜的離子交換容量增加。而PMMA/2M2HT MMT複合薄膜則是有測出一些離子交換容量。
在PMMA/2M2HT MMT複合薄膜酚化合物之批式吸附部份,當2M2HT MMT/ PMMA重量比值增加時,薄膜對酚化合物之吸附量增加,這是因為由2M2HT MMT所製備出來的薄膜是疏水性的,薄膜與酚化合物之間會產生疏水作用力。而且薄膜對p-nitrophenol之吸附量大於對酚之吸附量,可能是因為p-nitrophenol比較疏水的關係。另外,經由乾式相轉移法製備出來的薄膜對酚化合物的吸附效果會比由乾濕式製備出來的薄膜來的好。在脫附的部份,薄膜的脫附率都可以達到70%以上,而且以99.9 wt%甲醇溶液當做脫附劑的脫附效果比50 wt%乙醇水溶液脫附效果還要好。

In this study, poly(methyl methacrylate) (PMMA)/ montmorillonite composite membranes were prepared via two phase inversion methods - vapor induced phase separation (VIPS) and nonsolvent induced phase separation (NIPS). The resulted membranes with different feed MMT/PMMA (M/P) weight ratios were characterized by ATR-FTIR, TGA, SEM, contact angle, OM, and water content. The ATR-FTIR spectra revealed the successful introduction of characteristic Si-O-Si group of MMT in the composite membranes. The experimental M/P weight ratios analyzed by TGA were in close agreement with the feed M/P ratios. But in the TGA results of PMMA/Na+-MMT composite membranes, the membrane which was fabricated in NIPS lost so much Na+-MMT. Moreover, the contact angle and water content results for the PMMA/2M2HT MMT composite membranes show that they were more hydrophobic than the PMMA membranes. The contact angle and water content results for the PMMA/Na+-MMT composite membrane were showed that they were more hydrophilic than the PMMA membranes without Na+-MMT. In ion exchange capacity experiment, the ion exchange capacity was increased with increasing Na+-MMT/PMMA weight ratio. PMMA/2M2HT MMT composite membranes had a bit ion-exchange capacity. For batch adsorption of phenol compounds, the composite membranes exhibited higher adsorption capacities than the PMMA membrane, which should result from the introduction of 2M2HT MMT. The adsorbed amount of phenol compounds increased with increasing M/P ratio in membrane. In addition, the adsorption performance for the PMMA/2M2HT MMT composite membranes prepared from VIPS was better than those prepared from NIPS. In the batch desorption process, the desorption percentage was above 80% by using 99.9 wt% methanol, and above 70% by using 50 wt% ethanol.
