Membrane-Based Separation Technologies for Water Treatment, Desalination, and Gas Capture
This research community develops advanced membrane materials and processes to separate liquids and gases, primarily for purifying water, desalinating seawater, treating wastewater, and capturing carbon dioxide.
The work centers on the design and fabrication of composite membranes, with a heavy focus on polyvinylidene fluoride (PVDF) and graphene oxide as key materials. Recurring methods include nanofiltration, reverse osmosis, ultrafiltration, and membrane distillation. Specific applications named in the literature include oil-water separation, wastewater treatment, and gas separation. The research frequently addresses the challenge of antifouling performance and the enhancement of permeability and selectivity through mixed-matrix and nanocomposite structures.
The largest share of the community's output is found in fluorine research, accounting for 3.0% of all fluorine studies, with 5,750 papers in this group. Carbon research follows with 5,752 papers, representing 0.6% of all carbon studies.
The community comprises 23,232 papers, publishing most frequently in the Journal of Membrane Science, Separation and Purification Technology, and Desalination. Recent work continues to focus on engineering pore sizes in ceramic and polymeric membranes, developing stimuli-responsive materials for oil-water separation, and applying mixed-metal-organic frameworks to enhance membrane stability and selectivity in harsh environments.
