Fabrication of high performance TFN membrane containing NH2-SWCNTs via interfacial regulation
A high-flux thin film nanocomposite (TFN) nanofiltration (NF) membrane for low pressure operation (3.5 bar) was fabricated by blending purified amino-functionalized single-walled carbon nanotubes (NH2-SWCNTs) with piperazine (PIP) as aqueous phase monomers through interfacial polymerization (IP). The surface properties and structures of the polyamide (PA) active layer were suitably tailored by introducing different amounts of NH2-SWCNTs into the PA layer. It was found that the homogeneous incorporation of NH2-SWCNTs facilitated a more integral PA layer along with improved roughness, hydrophilicity, and surface charge of the modified membranes, which could be validated by membrane characterisation including SEM, AFM, ATR-FTIR, XPS, zeta potential and water contact angle measurements. Based on cross-flow NF tests, the optimized ultra-thin NH2-SWCNT-TFN membranes with 0.002 wt% of NH2-SWCNTs exhibited outstanding water permeability of up to 17.8 L m(-2)h(-1)bar(-1), 71.1% higher than that of the pristine membrane, along with high MgSO(4)rejection of 91.0% and Na(2)SO(4)rejection of 96.34%. Meanwhile, NH2-SWCNT-TFN membranes also showed excellent long-term stability and antifouling ability. This work demonstrates a facile strategy to fabricate a scalable, low-pressure and ultra-thin TFN membrane with excellent performance.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 5308-25-8. Product Details of 5308-25-8.
