Selective Adsorption and Separation through Molecular Filtration by Hyperbranched Poly(ether amine)/Carbon Nanotube Ultrathin Membranes

摘要: In response to the increasing public awareness of serious dye-contained wastewater contamination, we herein fabricated a novel anthracene-containing hyperbranched poly(ether amine) (hPEA-AN)/carbon nanotube (CNT) ultrathin membrane (UTM), which combined both merits conventional dye adsorption strategy and filtration process, implement efficient selective molecules also separation mixtures by molecular filtration. Taking advantage π–π stacking interactions between anthracene CNT sidewalls hydrophobic interactions, CNTs were coated tightly with hPEA-AN form hPEA-AN@CNT complex, can be well-dispersed very stably in water. The formation complex was confirmed using X-ray photoelectron spectroscopy, Raman spectra, fluorescence thermogravimetric analysis. Meanwhile, simple process applied prepare UTMs thickness 1.5 μm, further cross-linked thro...
