By a News Reporter-Staff News Editor at Journal of Technology -- A new study on Applied Polymer Science is now available. According to news reporting originating from Shanghai, People's Republic of China, by VerticalNews correspondents, research stated, "Using poly(vinyl alcohol) (PVA) with highly hydrophilic properties as membrane material and poly(ethylene glycol) (PEG) as an additive, we prepared PVA/tetraethoxysilane (TEOS) ultrafiltration (UF) membranes with good antifouling properties by a sol-gel method. The PVA/TEOS UF membranes were characterized by X-ray diffraction patterns, Fourier transform infrared spectroscopy, scanning electron microscopy, and static contact angle of measurement of water."
Our news editors obtained a quote from the research from the East China University of Science and Technology, "The hybridization of TEOS to PVA for preparing the PVA/TEOS UF membranes achieved the required permeation performance and good antifouling behaviors. The morphology and permeation performance of the PVA/TEOS membranes varied with the different TEOS loadings and PEG contents. The pure water fluxes (J(W)) increased and the rejections (Rs) decreased with increasing TEOS loading and PEG content. The PVA/TEOS UF membrane with a PVA/TEOS/PEG/H2O composition mass ratio of 10/3/4/83 in the dope solution had a J(W) of 66.5 L m(-2) h(-1) and an R of 60.3% when we filtered it with 300 ppm of bovine serum albumin aqueous solution at an operational pressure difference of 0.1 MPa."
According to the news editors, the research concluded: "In addition, the filtration and backwashing experiment proved that the PVA/TEOS membranes possessed good long-term antifouling abilities."
