Polymer Nanocomposite Membranes for Antifouling Nanofiltration
Recent Patents on Nanotechnology, 2016Fouling refers to the unwanted and undesirable attachment of biological macromolecules, inorganic, organic matter, and microorganisms on water contact surfaces. Fouling reduces the performance of devices involving these submerged surfaces and is considered the bottle-neck issue for various applications in the biomedical industry, food processing, and ...

A Novel Process for the Fabrication of Nanocomposites Membranes
Journal of Nanoscience and Nanotechnology, 2009The combination of electrospinning and electrospraying techniques for the deposition of inorganic nanoparticles over polymeric nanofibers to create novel multifunctional nanomaterials has been carried out. The combination of these two techniques is essential because by conventional mixing of nanoparticles with polymers and then electrospinning resulted

Nanocomposite membranes for the removal of dyes
2022The scarcity of affordable, sustainable, safe, and clean water is one of the major challenges faced by the world. The use of polymeric membranes in wastewater treatment has become a major solution in fighting water scarcity. Some of these membranes (microfiltration, ultrafiltration, and nanofiltration) operate at low pressure when compared to reverse ...

Alumina membranes — templates for novel nanocomposites
Applied Organometallic Chemistry, 1998Three different examples have shown that nanoporous alumina membranes serve as ideal templates for the formation of nanostructured materials and also as a support of those materials in composites. The unique properties of such membranes (transparency, chemical resistivity, thermal stability, adjustable pore sizes etc.) and the very simple mode of ...

Characterization of Nanocomposite Polymeric Membrane
Journal of Polymer Research, 2006Composite membrane has good permeability and selectivity for gases, which depends upon the operating conditions. The solubility and diffusivity of the penetrant in the polymer matrix control the transport through non-porous dense membrane. In the present work, the nano sized particles of Co0.6Zn0.4Fe2O4 were prepared by the co-precipitation method and ...

Organic/Zeolites Nanocomposite Membranes
2017There are different types of fuel cells, but Polymer Electrolyte Membrane (PEM) Fuel Cells are one of the most promising because they are low-temperature fuel cells. The solid polymer electrolyte has to present transport selectivity, besides the ion conductivity; thus in case of using in fuel cells, the membrane must let the hydrogen ions pass easily ...
