Abstract：A novel thin-film nanocomposite membrane was fabricated by interfacial polymerization for the forward osmosis (FO) application. Fullerenol (C60(OH)n), with n consisting of 24 - 28 was incorporated into the active layer to enhance the FO membrane performance. Different concentrations of fullerenol loading (100, 200, 400 and 800 ppm) were added to the top skin layer. The structural and surface properties of the pure thin-film composite membrane (TFC) and fullerenol-incorporated thin-film nanocomposite (FTFC) membranes, were characterized by ATR-FTIR, SEM, and AFM, respectively. FO performance and separation properties were evaluated in terms of water flux, reverse salt flux, antifouling propensity, water permeability and salt permeability for all TFC and FTFC membranes. Osmotic performance tests showed that FTFC membranes achieved higher water flux and reverse salt flux selectivity compared with those of TFC membrane. The FTFC membrane with a fullerenol loading of 400 ppm exhibited a water flux of 26.1 LMH, which is 83.03%-fold higher than that of TFC membrane with the specific reverse salt flux of 0.18 g/L using 1 M sodium chloride draw solution against deionized water in FO mode.

摘要：本研究通过界面聚合法制备了一种新型的TFN正渗透膜，通过将不同负载量（100,200,400和800ppm）的富勒醇(C60(OH)n，n=24-28)掺杂到活性层中以提高其性能。通过ATR-FTIR，SEM和AFM分别对未改性复合膜（TFC）和掺入富勒醇的薄膜纳米复合材料（FTFC）膜的结构和表面性能进行了表征。膜的正渗透和分离性能通过水通量，反向盐通量，防污性，透水性和盐渗透性进行评估。渗透性能测试表明，与TFC膜相比，FTFC膜具有更高的水通量和反向盐通量。400ppm富勒醇负载量的FTFC膜显示出26.1LMH的水通量，其比TFC膜的水通量高83.03％（0.18g / L的反向盐通量，1M NaCl汲取溶液，去离子水为原料液，FO模式）。实验表明， FTFC膜中的富勒醇掺杂也有助于降低膜的结垢倾向。
