摘要：This study aims to develop an advanced organic solvent nanofiltration (OSN) membrane by incorporating an adamantane-amide active layer through a modified structure rearrangement process (mSRP) combined with host-guest interactions. The membrane was fabricated by treating a commercial reverse osmosis (RO) membrane with solutions containing polysaccharides and adamantane monomers, obtaining significantly enhanced separation performance. The modified membrane exhibited a "mesh-like" morphology and increased surface roughness which contributed to substantially higher permeability and retention rates compared to those of pristine RO membrane. Specifically, the optimal membrane attained a permeability of 9.3 L m-2 h-1 & sdot;bar-1, representing an increase by 111.4 % relative to the pristine membrane, while maintaining a rejection rate of 94.0 % for the commonly used erythromycin antibiotic. The rearrangement behavior and mechanism of the host-guest interactions were investigated using density functional calculations. Long-term operational tests confirmed the stability of the membrane and its potential for industrial applications. This study introduced a novel approach for upgrading commercial RO membranes for efficient OSN applications, thereby contributing to the development of sustainable separation technologies in the biomedical sector.
