The fully biobased flame retardant, which is based on the green and convenient ionic reaction of phytic acid (PA) and taurine (TA) in water, brings flame retardancy to polylactic acid (PLA) efficiently. PLA composite passes UL-94 V-0 rating in vertical combustion successively with only 0.5 wt % reactant of PA and TA (PA-TA). Moreover, the peak heat release rate (PHRR) and the total heat release rate (THR) of PLA composite are reduced by 13.1 and 10.0% with 5.0 wt % PA-TA. Moreover, the elongation at break of PLA with 5.0 wt % PA-TA is 92.7% higher than that of pure PLA due to the ultralow addition and the interaction of hydrogen bonds between the flame retardant and the matrix material. The resultant fully biodegradable flame-retardant PLA composites reported here could be widely applied in electronic appliances, automobiles, and other fields.

通过植酸和牛磺酸之间的离子反应专用于聚乳酸的超低添加生物基阻燃剂

全生物基阻燃剂基于植酸(PA)和牛磺酸(TA)在水中的绿色便捷离子反应,有效地为聚乳酸(PLA)带来阻燃性。PLA 复合材料在垂直燃烧中连续通过 UL-94 V-0 等级,PA 和 TA (PA-TA) 反应物仅为 0.5 wt%。此外,PLA复合材料的峰值放热率(PHRR)和总放热率(THR)在PA-TA含量为5.0%的情况下分别降低了13.1%和10.0%。此外,由于超低添加量以及阻燃剂与基体材料之间氢键的相互作用,含有 5.0 wt% PA-TA 的 PLA 的断裂伸长率比纯 PLA 高 92.7%。所报道的完全可生物降解的阻燃PLA复合材料可广泛应用于电子电器、汽车等领域。
