Electrochemical strain microscopy (ESM) and conductive atomic force microscopy (C-AFM) are used to create and examine polymer composite electrolytes of Nafion and phosphotungstic acid (PWA) in order to see the hydrophilic ion channels near the surface, which are made up of water and sulfonic acid groups.
The findings show that the fibrillar objects in the ESM image are hydrophilic ion channels and additional ion channels created by interaction between PWA and sulfonic groups in Nafion, without major topographic alterations. Through the combined use of ESM and C-AFM, the buried ion channels beneath the surface as well as the intake and exit of the channels on the surface are investigated in this study. The findings improve our knowledge of ionic conduction in composite polymer electrolytes in a variety of fields.
Can fast salt ion transport be achieved by membranes with narrow molecular-sized channels and hydrophilic properties?
Here, we present a novel method for constructing membranes that have strong size-exclusion selectivity for tiny organic compounds, narrow molecular-sized channels, and hydrophilic functionality.
What function do AO-PIMS' hydrophilic ionizable groups serve?
These findings imply that the hydrophilic ionizable groups in AO-PIMs are crucial in lowering ion transport resistance and enabling RFBs to function effectively. Fig. 4: Aqueous redox flow batteries can operate effectively and steadily thanks to hydrophilic microporous membranes
What are electrogenic ion pumps?
an ion pump that produces a net charge flow as it operates. Na+-K+ All animal cells have an enzyme called ATPase, which pumps potassium into cells while removing sodium from cells, in the plasma membrane.
