The fabrication of conventional or biodegradable polymers with improved thermal and fire-resistant properties is an important task for their successful application in various branches of the industry. In this work, few-layered molybdenum disulfide was functionalized with 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide and introduced into polyethylene and poly(lactic acid) matrixes. The obtained polyethylene composite samples displayed improved thermal stability, significant reduction in CO emissions, improved fire-resistant properties, and over 100% increases in thermal conductivity. Poly(lactic acid) composites displayed less impressive results, but have managed to improve some values, such as CO emissions, peak heat release rate, and total heat release in comparison to pristine polymer.
制备具有改善的热性能和耐火性能的传统聚合物或可生物降解聚合物，对于它们在各个工业领域的成功应用而言是一项重要任务。在这项工作中，将几层二硫化钼用9,10-二氢-9-氧杂-10-磷杂菲-10-氧化物进行功能化处理，并引入到聚乙烯和聚乳酸基体中。所得到的聚乙烯复合材料样品表现出改善的热稳定性、显著降低的一氧化碳排放量、改善的耐火性能以及热导率提高超过100%。聚乳酸复合材料的结果虽不那么令人印象深刻，但与原始聚合物相比，已成功改善了一些数值，如一氧化碳排放量、峰值热释放速率和总热释放量。
