摘要:
Membrane separation technology has been widely applied in material separation fields. However, it still has the disadvantage of poor selectivity at nanometer and sub-nanometer scales. Here, two kinds of pillar[6]arene with opposite charges were prepared by modification, and the aligned nanochannel composite membrane was successfully constructed by directional assembly on a negatively charged silicon interface. The precise sieving properties of aligned channels were studied using the xylene isomer as a model molecule. It has been proved that the...
