This review synthesizes the current state of knowledge of the dominant degradation mechanisms acting on PEMs, namely mechanical stress, thermal degradation, and chemical attacks by reactive oxygen species (ROS). It is concluded that although mechanical degradation brought about by varying pressure and hydration cycles, membrane reinforcement with materials such as expanded polytetrafluoroethylene (ePTFE) and diverse composite membranes has somewhat mitigated the structural strength and toughness. Thermal and chemical degradation remains as principal challenges which are most often hastened by elevated temperatures and formation of reactive free radicals such as hydroxyl and hydrogen peroxide. Hence, to counteract chemical degradation, the addition of radical scavengers like cerium oxide (CeO₂) and manganese-based additives can scavenge the destructive species even before this cause significant damage. Other new materials for PEM such as perfluorosulfonic acid (PFSA) composites have demonstrated enhanced resistance in chemical environments and a longer life. This includes research on innovative approaches such as introducing ionomers with improved thermal stability and evaluating hybrid organic-inorganic membranes in fighting the degradation mechanism of thermal degradations. This review brings out the need to understand the degradation mechanisms and advance mitigation strategies to ensure elongation of PEMFCs' life, thus paving a way for their reliability and feasibility as clean energy.</div></div>","PeriodicalId":18322,"journal":{"name":"Materials Today Sustainability","volume":"30 ","pages":"Article 101103"},"PeriodicalIF":7.1,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143768921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study introduces an innovative piezoelectric composite material integrating PVDF-HFP (polyvinyl fluoride–hexafluoropropylene) and barium titanate (BTO) nanocrystals. Specifically engineered for efficient pollutant degradation and bacterial removal, this composite demonstrates promising capabilities in environmental remediation. Under ultrasound stimulation, BTO exhibits exceptional production of Reactive Oxygen Species (ROS), further enhanced by the biocompatibility of the PVDF-HFP membrane, which promotes ROS generation and cellular adhesion. The synergistic effect of these components significantly enhances ROS production efficiency, achieving a remarkable degradation rate of approximately 99 % for Congo Red in just 70 min under soft ultrasound. Scavenger experiments confirm hydroxyl radicals as pivotal in this process. Furthermore, the composite piezo catalyst displays robust durability across multiple experimental cycles, highlighting its practical applicability. Its high polarizability enables efficient piezoelectric power generation (≈5.03 V) through simple mechanical stimulation, yielding substantial instantaneous voltage output. Additionally, the material exhibits potent antibacterial activity achieving nearly 99 % bacterial eradication within a brief 30-min time frame.

The fabrication duration and physical and mechanical characteristics of samples were assessed and compared to those made of pure hemp hurds substrates. The results showed that samples made of hybrid substrates exhibited longer production duration than those from 100 % hemp hurds.
