Abstract

The increasing concerns about solid waste disposal have led to the development of innovative strategies for repurposing waste materials. This paper describes a simple solution casting process for recycling postconsumed footwear leather fiber (PCF) into a biocomposite film reinforced with graphene oxide (GO) and polyvinylpyrrolidone (PVP). PVP was utilized as a compatibilizer to strengthen the interfacial bonding of GO and leather fiber via π–π interactions. UV–visible spectroscopy, Fourier transform infrared spectroscopy, X-ray diffraction, thermogravimetric analysis, and scanning electron microscopy were used to examine the material dispersibility bonding between GO and PCF, structural properties, thermal properties, and surface morphology of the biocomposite films, respectively. Compared to pure PCF film, the oxygen transmission rate of the prepared biocomposite films is elevated by 64% as well as the biodegradability rate is intensified up to 60%. In addition, the film’s tensile strengths are raised by 216%, while their elongation at break is increased by 164.64% as compared with PCF. The versatility of these eco-friendly and biodegradable composite films extends to its possible applications in packaging and interior design. The outcomes of the research reveal the viability of manufacturing affordable and sustainable biocomposites through the utilization of waste leather from consumed footwear.

氧化石墨烯增强生物复合材料的制备:废弃鞋履皮革的回收

对固体废物处理的日益关注已导致制定重新利用废物材料的创新战略。本文介绍了一种简单的溶液铸造工艺，将消耗后的鞋类皮革纤维(PCF)回收成氧化石墨烯(GO)和聚乙烯吡罗烷酮(PVP)增强的生物复合膜。PVP作为相容剂，通过π -π相互作用增强氧化石墨烯与皮革纤维的界面键合。利用紫外-可见光谱、傅里叶变换红外光谱、x射线衍射、热重分析和扫描电镜等技术分别考察了氧化石墨烯与PCF之间的材料分散性、键合性能、结构性能、热性能和表面形貌。与纯PCF膜相比，制备的生物复合膜的透氧率提高了64%，生物降解率提高了60%。与PCF相比，薄膜的抗拉强度提高了216%，断裂伸长率提高了164.64%。这些生态友好和可生物降解的复合薄膜的多功能性延伸到其在包装和室内设计中的可能应用。研究结果表明，通过利用消费鞋类的废皮革，制造价格合理且可持续的生物复合材料是可行的。
