However, the development of biodegradable TENGs remains a formidable challenge. This study presents the preparation of a tribopositive material entirely composed of biodegradable poly(butylene adipate-co-terephthalate) (PBAT) polymer enhanced with CoFe<sub>2</sub>O<sub>4</sub> (CF) nanoparticles. The CF nanoparticles, synthesized via the combustion method, were incorporated into the PBAT matrix through solvent casting to form films with varied filler content (0.2, 0.4, 0.6, 0.8, and 1 g). The CF nanoparticles structural, surface, and electrical properties were characterized using XRD and FTIR spectroscopy. At the same time, the morphology of the nanomaterials and their composites was analyzed by scanning electron microscopy. Specifically, the 0.8 g PBAT-CF TENG demonstrated superior performance, achieving an output voltage of 45.45 V and a current of 4.5 µA. Subsequent electrical studies, including charging commercial capacitors (1.0 to 47 μF) and powering LEDs and calculators, underscored the device’s efficiency. The PBAT-CF TENG also effectively generated voltage and current signals from physical activities like walking and jumping. This innovative approach highlights the potential for biodegradable, high-performing, self-powered flexible electronics, and wearable devices, paving the way for sustainable technological advancements.</div></div>","PeriodicalId":14236,"journal":{"name":"International Journal of Polymer Analysis and Characterization","volume":"29 8","pages":"Pages 685-698"},"PeriodicalIF":1.7,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142592610","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Also, increasing ash gourd peel particle fraction increases the water absorption of composites when immersed in distilled, sea, and tap water. The composite with 5% filler by weight absorbs water at a minimal rate when immersed in seawater.
