摘要

绿色阻燃剂的开发已成为材料科学家和技术人员关注的核心部分,从通用到特定可持续产品的范式转变。这是首次报道将咖啡生物废弃物作为环氧树脂的可持续阻燃剂,环氧树脂是一种典型的高度易燃的聚合物。我们使用废咖啡渣(SCG)和磷化学改性的咖啡渣(P-SCG)来开发一种可持续的高效阻燃剂。在热解燃烧流量热分析(PCFC)中观察到热释放率(pHRR)峰值降低了40%,这证明了用过的咖啡生物废弃物作为聚合物可持续阻燃剂的优点。这项工作将为研究其他种类的咖啡废物而不是来自咖啡工业不同部门的SCG对不同家族聚合物的影响开辟新的机会。

Coffee Wastes as Sustainable Flame Retardants for Polymer Materials
Development of green flame retardants has become a core part of the attention of material scientists and technologists in a paradigm shift from general purpose to specific sustainable products. This work is the first report on the use of coffee biowastes as sustainable flame retardants for epoxy, as a typical highly flammable polymer. We used spent coffee grounds (SCG) as well as SCG chemically modified with phosphorus (P-SCG) to develop a sustainable highly efficient flame retardant. A considerable reduction in the peak of heat release rate (pHRR) by 40% was observed in the pyrolysis combustion flow calorimeter analysis (PCFC), which proved the merit of the used coffee biowastes for being used as sustainable flame retardants for polymers. This work would open new opportunities to investigate the impact of other sorts of coffee wastes rather than SCG from different sectors of the coffee industry on polymers of different family.
