近日,中国科学院重庆绿色智能技术研究院膜技术与应用工程中心在自支撑氧化石墨烯纳米复合正渗透膜方面取得研究进展。内浓差极化和膜污染是正渗透膜技术在实际应用中的难点,改变膜表面及支撑结构可以提高正渗透膜的性能。该研究将石墨烯和三乙酸纤维作为复合膜材料,研制出了自支撑
Recently, the Research Center of Membrane Technology and Application Engineering, Chongqing Institute of Green Smart Technology, Chinese Academy of Sciences has made research progress in self-supporting graphene oxide nanocomposite positive osmosis membrane. Intrinsic concentration polarization and membrane fouling are the difficulties in the practical application of the positive osmosis membrane technology. Changing the membrane surface and the supporting structure can improve the performance of the positive osmosis membrane. The study of graphene and triacetate fibers as a composite membrane material, developed a self-supporting
