CGE Healthcare’s ePTFE membrane (expanded PTFE membrane) offers protection against liquid and air-borne contaminants. In the challenging and harsh environments it provides an increased performance. It is suitable for all the applications which include strong acids, organic solvents, and strong alkalis.

Polymer electrolyte membrane fuel cells (PEMFCs) have attracted great attention in the last two decades as valuable alternative energy generators because of their high efficiencies and low or null pollutant emissions. In the present work, two gas diffusion electrodes (GDEs) for PEMFCs were prepared by using an ink containing carbon-supported platinum in the catalytic phase which was sprayed

The good thermal efficiency of the hydrophobic nanowood membrane was ascribed not only to its super low thermal conductivity (0.080 versus 0.30 ± 0.02 W m −1 K −1 for natural wood membrane at 60°C) but also to its high porosity (89 ± 3% versus 21 ± 3%) and bigger

2017/12/15 · Polytetrafluoroethylene (PTFE) membrane used in this study was Advantec PTFE membrane filter from Toyo Roshi Kaisha, 47 mm in diameter and 3.0 μm in pore size. Disperse red 1 [N-ethyl-N-(2-hydroxyethyl)-4-(4-nitrophenylazo)aniline], disperse blue 14 [1,4-Bis(methylamino)anthraquinone] and rhodamine B ( Fig. 3 ) were obtained from Sigma-Aldrich Co. LLC.

From the circuits in the cameras on space missions to the next generation of photovoltaic cells, DuPont™ Kapton® polyimide films are helping make extraordinary new design possibilities actually happen. For applications where extremes of heat and vibration are the norm, designers rely on Kapton® because of its ability to maintain its unique

2020/8/12 · Abstract The aim of this study was to observe the atmospheric pressure plasma for polytetrafluoroethylene (PTFE) surface modification. The hydrophilicity of the effectively-anchored acrylic acid polymerization on the PTFE surfaces through atmospheric pressure plasma-grafted polymerization was examined using surface chemical composition analysis. The hydrophilic acrylic …
