Publication of a new article on ACS Polymers Au about electrospun membranes of PVDF with high operative long-term resistance under hydrodynamic stress.
Universitat de València MATS Group (Materials Technology and Sustainability) Membrane Development for Environmental Technologies line of research announces the publication of a new research article on ACS Polymers Au scientific paper (ACS Publications)
The project, named PVDF Nanofiber Membranes for Dissolved Methane Recovery from Water Prepared by Combining Electrospinning and Hot-Pressing Methods presents the development of flat membrane made of PVDF electrospun nanofiber put under thermic posttreatment using hot-pressing, aimed to its application in membrane contactors for the retrieval of methane dissolved in water
The study explores the effect of variables such as temperature, pressure and thermic posttreatment duration, proving that controlled pressing provides hydrophobic membranes with better integrity between fibers and enough porus size to avoid wetting without worsening the membrane performance in the methane separation.
These characteristics allow a stable operation by extracting methane from the supply currents with carrier gas, resisting up to 8 hours of accumulated separation. This focus reaffirms the commitment of the group with clean technology development for the mitigation of greenhouse gases.
The study was carried out within the CarbonBrane (PID2021-1224950A-I00) and MethBrane (TED2021-131276 A-I00) research projects and represents the first publication part of the doctoral thesis Félix Eduardo Montero Rocca, Universitat de València Chemical Environmental and Process Engineering, funded by Generalitat Valenciana, Spain (CIACIF/2022/386).
