摘要
Abstract
A series of polysulfone (PSf)/polyaniline-Pluronic F127 (PANI-F127) composite ultrafiltration membranes, using two polymers namely PANI nanofibers and triblock copolymer Pluronic F127 with different modifying mechanisms as co-additives, were prepared via immersion precipitation method. The effects of the co-additives on membrane structure and performance were systematically investigated, compared and analyzed. Membrane structure was characterized by Fourier transform infrared spectroscopy (ATR-FTIR) , X-ray photoelectron spectroscopy (XPS), energy dispersive X-ray spectroscopy (EDS), scanning electron microscope (SEM), porosity, and contact angle measurement. Membrane performance was evaluated by pure water flux, protein rejection, antifouling property and additive stability. Results demonstrate that Pluronic F127 was more effective in improving membrane hydrophilicity, while PANI nanofibers played an important role in increasing membrane porosity and decreasing surface pore size and skin layer thickness. Furthermore, it was found that the interaction between PANI nanofibers and Pluronic F127 has synergistic effects on improving membrane performance and depressing the defects such as large addition amount, low rejection and poor additive stability when using Pluronic F127 as the additive.关键词
