WitrynaNovel nanostructured organo-modified layered materials based on graphene oxide carrying various hydrophilic functional groups (-NH(2), -OH, -SO(3)H) are prepared and tested as nanofillers for the creation of innovative graphene-based Nafion nanocomposites. The hybrid membranes are characterized by a combination of … Witryna24 mar 2024 · Paper published Mar 24, 2024 link to journal; full text (PDF) Hydrophilic materials such as Nafion can nucleate the buildup of interfacial water, which shows features different from bulk water. We investigated the effect of infrared (IR) light on a …

WitrynaNafion ionomer, composed of hydrophobic perfluorocarbon backbones and hydrophilic sulfonic acid side chains, is the most widely used additive for preparing catalyst layers (CLs) for electrochemical CO2 reduction, but its impact on the performance of CO2 … Witrynaal. [13], [14] demonstrated that a hydrophilic MPL, consisting of vapor-grown carbon fibers and ionomer, facilitated favourable fuel cell performance at both dry and wet conditions. Ahn et al. [15] showed that a hydrophilic MPL with carbon black and … photo of one rose

Witryna1960s, DuPont developed membranes from Nafion, a co-polymer of perfluoro-sulfonic acid with hydrophobic fluorocarbon backbone and hydrophilic sulfonic acid pendent side chains. This membrane was primarily used as a perm-selective separator in chlor … WitrynaBesides, other hydrophobic–hydrophilic phase-separated polymers have also been synthesized as new kinds of proton-exchange membrane though they did not perform as well as Nafion., ... Meanwhile, the selectivity of Nafion-Cage 3 composite membrane … WitrynaPerfluorosulfonic acid Nafion membranes are widely used as an electrolyte in electrolysis processes and in fuel cells. Changing the preparation and pretreatment conditions of Nafion membranes allows for the optimization of their properties. In this work, a … how does nutanix work
