Alumina membranes — templates for novel nanocomposites

Applied Organometallic Chemistry, 1998
Three 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 ...

Nanocomposite pervaporation membrane for desalination

Chemical Engineering Research and Design, 2020
Abstract Desalination via pervaporation has been considered as an attractive membrane process for obtaining clean water from non-potable saline sources, which has advantages, i.e., it is superior in salt rejection and has the capability of coping with high-salinity feed solutions.

Characterization of Nanocomposite Polymeric Membrane

Journal of Polymer Research, 2006
Composite 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

2017
There 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 ...
