英文摘要: Abstract(#br)In this work, annular supramolecular cucurbit[6]uril (CB6) and dendritic polyamidoamine (PAMAM) were employed to construct high-performance nanofiltration (NF) membranes via one-step interfacial polymerization (IP) process. The obtained membrane features not only the enlarged polyamide tunnels based on the large steric hindrance of CB6 and PAMAM but also the novel hydrophobic rotaxane tunnels based on the host-guest chemistry between CB6 and piperazine (PIP) or PAMAM. The CB6/PAMAM-modified membrane achieved nearly four times enhancement of pure water permeability (PWP) compared to the unmodified traditional membranes with still high Na 2 SO 4 rejection. This indicates the positive contribution of CB6/PAMAM-modification to overcome the “trade-off” effect limiting NF...
