The β-cyclodextrin-modified graphene oxide nanosheets (CMCD@GO), linked by chemical bonds, was successfully prepared. With it was used as fillers, the new CMCD@GO/Polyether sulfone (PES) mixed matrix membrane (CMCDGOM) was prepared by the non-solvent induced phase inversion method. FTIR, XRD and Raman Spectroscopy were used to demonstrate that CMCD@GO was successfully prepared. And the changes in the cross section and surface roughness of the CMCDGOM were observed using SEM and AFM. The modified CMCDGOM showed the larger and continuous pore size, lower surface roughness, and thinner "active layer", compared to the original GO-loading membrane (GOM). Next, the test results of the interface parameter integrated measurement system showed that the water contact angle of CMCDGOM was reduced to 50.8 ° (with GOM was 60.9 °). Then, through the experiments on the treatment of simulated oil sands produced water (OSPW), we have demonstrated the modified CMCDGOM had the higher removal efficiency (from 87.2 to 94.6%), better hydrophilicity (J_w =117.3 L•m⁻²•h⁻¹, 4 bar), more excellent anti-fouling and sustainable performance (higher flux recovery and lower total flux reduction) than the original COM. The results indicated that the introduction of CMCD@GO can significantly enhance the OSPW treatment capacity of original GO mixed matrix membrane.

成功制备了通过化学键连接的β-环糊精修饰的氧化石墨烯纳米片（CMCD @ GO）。采用非溶剂诱导相转化法制备了新型CMCD @ GO /聚醚砜（PES）混合基质膜（CMCDGOM）。FTIR，XRD和拉曼光谱被用来证明成功制备了CMCD @ GO。并用SEM和AFM观察了CMDCGOM的截面和表面粗糙度的变化。与原始的GO加载膜（GOM）相比，改性的CMCDGOM显示出更大且连续的孔径，更低的表面粗糙度和更薄的“活性层”。接下来，界面参数综合测量系统的测试结果表明，CMDCGOM的水接触角减小到50.8°（GOM为60.9°）。然后，_瓦特= 117.3 L•米^-2 •水平^-1，4巴），更优良的防污和可持续的性能（较高的通量恢复并降低总磁通量减少）比原来的COM。结果表明，引入CMCD @ GO可以显着提高原GO混合基质膜的OSPW处理能力。
