Molecular-Recognition Membranes and Electrodes

CTS-9423090查尔斯·马丁公司州立大学将开发用于分离的新型分子识别膜。复合膜由沉积在微孔支撑膜表面的化学选择性聚合物的超薄膜(厚度小于100 nm)组成。选择性膜将由分子印迹聚合物(MIP)组成。MIPS是通过模板聚合制备的，该模板聚合产生选择性地结合印刷分子的位点。将合成纳米孔而不是大孔的超薄MIP薄膜。合成条件对印迹溶质的选择性和传输速率的影响将被确定。这一研究可能为开发具有高选择性的纳滤膜奠定基础。所提出的膜在生化和石化分离以及传感器技术中具有潜在的应用前景。

CTS-9423090 Charles Martin CO State Univ. Novel molecular - recognition membranes will be developed for use in separations. The composite membranes consist of an ultrathin film (less than 100 nm thick) of a chemical selective polymer deposited onto the surface of a microporous supported membrane. The selective film will be composed of a molecularly-imprinted polymer (MIP). MIPs are prepared via template polymerization that yields sites which selectively bind the print molecule. Ultrathin MIP films that are nanoporous rather than macroporous will be synthesized. The effects of synthesis conditions on the selectivity and rate of transport of the print solute will be determined. The research may lead to the development of nanofiltration membranes with high transport selectivity. The proposed membranes have potential applications in biochemical and petrochemical separations as well as sensor technology.
