The cross-linking between Ph-PyOPBI and cPIL significantly improved the phosphoric acid (PA) uptake and proton conductivity of the resulting HT-PEMs. The cross-linked membranes were prepared with 10%, 20%, 30%, 40% of cPIL with respect to Ph-PyOPBI polymer weight and their HT-PEM properties were studied. All the four cross-linked membranes were found to be completely stable in 85% PA while the pristine Ph-PyOPBI membrane was stable only up to 75% PA. The reason for such remarkable stability of cross-linked Ph-PyOPBI in high acid concentration is due to the cross-linking interactions with the cPIL. The membrane containing 10% cPIL exhibited a proton conductivity of 0.053 S cm^–1 at 160 °C which is higher than the pristine Ph-PyOPBI membrane (0.015 S cm^–1 at 160 °C).</p><h3>Graphical abstract</h3><p>Proton Exchange Membrane (PEM) with improved properties for the use in high-temperature PEM fuel cell has been developed by cross-linking the pyridine-bridged polybenzimidazole chains through a cross-linkable polymeric ionic liquid.</p>\u0000<div><figure><div><div><picture><source><img></source></picture><span>The alternative text for this image may have been generated using AI.</span></div></div></figure></div></div>","PeriodicalId":616,"journal":{"name":"Journal of Chemical Sciences","volume":"138 2","pages":""},"PeriodicalIF":2.0,"publicationDate":"2026-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148009064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Stress is a feedback survival response that improves a person’s physical and mental health. An organism’s energy needs rise under stressful conditions, which leads to an increase in the production of free radicals. Oxidative stress is caused by the production of these free radicals. In the biomedical domain, malondialdehyde (MDA) is frequently employed as a biomarker for evaluating oxidative stress. In both &lt;i&gt;in vitro&lt;/i&gt; and &lt;i&gt;in vivo&lt;/i&gt; investigations, biomonitoring of MDA has been employed as a crucial biomarker for a number of disease patterns, including cancer, diabetes, atherosclerosis, heart failure and hypertension.
