Potentiometric membrane sensors are no exception. The approaches ensuring the long-term stability of their characteristics during the analysis of real media may be similar to those for protecting membranes in electrodialysis units. This work studies the electrode-active properties of homogeneous membranes based on a commercial copolymer of tetrafluoroethylene with sulfonated perfluorovinyl ether and novel grafted membranes based on a copolymer of polyvinylidene fluoride and sulfonated polystyrene in potentiometric sensors for the analysis of pharmaceuticals, artificial saliva solutions, and real samples of oral fluid. The patterns of change in the equilibrium and transport characteristics of the grafted membranes depending on the grafting degree and the conditions for polyaniline synthesis in them have been established. The results were compared with those for perfluorinated membranes. It was shown that polyaniline as a modifier of homogeneous and grafted sulfonated membranes increased their resistance to fouling due to its “cross-linking” effect on hydrophilic clusters and hydrophilization of the surface. The effect was achieved by suppressing the absorption of low-molecular-weight cations of drugs and metabolites with nitrogen-containing proton-acceptor groups, as well as the adsorption of high-molecular-weight components of physiological fluids.","PeriodicalId":700,"journal":{"name":"Membranes and Membrane Technologies","volume":"7 5","pages":"258 - 269"},"PeriodicalIF":1.6,"publicationDate":"2026-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147338706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been shown that the conductivity of the cation-exchange membranes is higher than that of the corresponding citric and malic acids solutions due to a higher concentration of hydrogen ions in the membrane phase. The conductivity of the anion-exchange membranes is significantly lower than that of the cation-exchange membranes, which is associated with a low mobility of organic anions. An atypical descending dependence of the specific conductivity of the anion-exchange membranes on the concentration of organic acids is discovered, caused by an increase in the concentration of low-mobility multiply charged organic ions in the membrane phase. The diffusion permeability of the anion-exchange membranes in organic acids solutions is much higher compared to the cation-exchange membranes due to the contribution of molecular acid diffusion and the high mobility of the hydrogen cation, the transfer of which limits diffusion in the case of anion-exchange membranes.

It was found that storage in juices leads to a decrease in the conductivity of anion-exchange membranes by up to 80% due to their conversion from the chloride form to the form of large organic ions and fouling by organic juice components. At the same time, the conductivity of cation-exchange membranes in tomato and apple juices changes less significantly. Based on the study of the current–voltage curves of membranes before and after their immersion in juices, it is shown that an increase in the length of the limiting current plateau is observed, caused by the sorption of organic components of various natures by the membranes, which is more pronounced for anion-exchange membranes. For the MK-40 membrane, this effect is absent. A method for membrane regeneration after contact with juices is proposed, which allows restoring the specific conductivity of the samples to their initial values.

Modification of the membrane surface by applying a nanostructured coating significantly expanded the operating capabilities of Pd membranes to low temperatures unattainable by analogs. This result was achieved by accelerating the limiting surface stages and, accordingly, shifting the influence of the diffusion stage toward lower temperatures. The obtained results were confirmed by data on the activation energy of the processes, according to which, due to surface modification, the activation energy was reduced by up to 2 times, compared to uncoated membranes. These results formed the basis for the mathematical model of hydrogen transport through Pd membranes at low temperatures developed in this study. This model takes into account the membrane surface roughness factor, which is an important criterion for the selected temperature range, where surface processes limit hydrogen transport. The obtained results suggest that the developed model is promising for predicting the efficiency of Pd-based membranes.","PeriodicalId":700,"journal":{"name":"Membranes and Membrane Technologies","volume":"7 3","pages":"185 - 194"},"PeriodicalIF":1.6,"publicationDate":"2026-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147337564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, promising materials are gel polymer electrolytes based on perfluorosulfonic acid cation-exchange membranes modified with inorganic fillers and solvated with aprotic solvents. This study addresses Nafion® composite membranes containing surface-sulfonated zirconia (sZrO2) and solvated with binary mixtures of ethylene carbonate (EC) with dimethylacetamide (DMAc), dimethylformamide (DMF), and dimethyl sulfoxide (DMSO) at a 1 : 1 ratio by volume. The presented systems demonstrate the dependence of ionic conductivity on the nature of the solvent, following the series: EC–DMAc > EC–DMF > EC–DMSO, with the maximum conductivity (2.2 mS/cm at 25°C) being achieved for the Nafion@sZrO2–EC–DMAc composition. The resulting electrolytes are electrochemically stable up to 4.2 V (vs. to Li+/Li), which makes them compatible with cathode materials such as LiFePO4 (LFP). However, DMSO slowly interacts with lithium metal to form a low-conductivity SEI layer, whereas EC–DMAc and EC–DMF systems provide stable operation of Li|Li cells for >1000 h at a current density of 0.1 mA/cm2. Cyclic tests of Li|LFP cells with Nafion@sZrO2–EC–DMAc and Nafion@sZrO2–EC–DMF electrolytes show an initial discharge capacity of ∼155 mA h/g (0.1C) and high stability—capacity loss after 50 cycles at 0.5C is 4.7 and 2.0%, respectively.
