Studies from Sichuan University Provide New Data on Membrane Science

February 25, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- Current study results on Membrane Science have been published. According to news originating from Chengdu, People's Republic of China, by VerticalNews correspondents, research stated, "The polytetrafluoroethylene nanofiber membranes for membrane distillation were prepared by sintering the precursor electrospun polytetrafluoroethylene/polyvinyl alcohol composite membranes. The effects of sintering temperature and time on the morphology and properties of the prepared membranes were investigated."

Our news journalists obtained a quote from the research from Sichuan University, "The prepared membranes were characterized by contact angles, lR and SEM to observe the structure evolution of the fibers during the sintering process. A unique moniliform structure was formed in proper conditions. The relationship between fiber morphology and membrane hydrophobicity, mechanical strength and porosity were discussed. The effect of membrane thickness on the liquid entry pressure was also studied to make sure the membrane was available in vacuum conditions. Moreover, membrane was tested in vacuum membrane distillation configuration."

According to the news editors, the research concluded: "The pure water flux and salt rejection were tested to evaluate the membrane permeability and separation property."
