In this letter, we are presenting a novel approach for the deposition of layer-by-layer (LbL) coatings capable of conferring flame retardant properties to flexible polyurethane foams exploiting subsecond deposition times. The process yields nanoscale coatings able to reduce by 33% one of the main fire safety parameters, namely the heat release rate peak, with a total treatment time of only 2.5 s. This new approach turned out to be three to 4 orders of magnitude faster than conventional LbL treatments. Such results make it possible for the exploit of LbL as a competitive, efficient and ecofriendly technology at industrial scale.
在这封信中，我们提出了一种新的方法，用于沉积层层（LbL）涂层，利用亚秒级的沉积时间为柔性聚氨酯泡沫赋予阻燃性能。该工艺可生成纳米级涂层，能够将主要消防安全参数之一的热释放率峰值降低 33%，总处理时间仅为 2.5 秒。这种新方法比传统的 LbL 处理快 3 到 4 个数量级。这些结果使得 LbL 能够在工业规模上作为一种具有竞争力、高效和环保的技术得到应用。
