Preparation of amorphous polyphenylsulfone nanofiltration membrane via thermally-induced lamination
Source abstract
Abstract
Abstract A novel approach to the fabrication of thin-film nanofibrous (TFN) membranes with high productivity was proposed, and a polyphenylsulfone (PPSU) TFN membrane was fabricated to address the low water permeability of PPSU membranes. The fusion of fibers with each other and with the selective top layer, which was evident in the scanning electron microscopy (SEM) images, gave rise to the structural stability of the membrane and enhanced permeability. Fourier transform infrared spectroscopy (FTIR), atomic force microscopy (AFM), thermogravimetric analysis (TGA), and tensile test were applied to study the membranes in terms of their properties. The efficiency of the PPSU TFN membranes was assessed in the filtration of an industrial wastewater and also a model foulant. Compared with a conventional PPSU membrane, the TFN membrane provided almost 2 times higher pure water flux (PWF) as well as about 4 times higher steady permeate flux without sacrificing the rejection percent.
