Layer-by-layer assembly often requires numerous deposition steps to obtain a suitable thickness for an effective flame retardant nanocoating. In an effort to make this technique more industrially feasible, an amine salt is added to the rinsing steps of a chitosan/sodium hexametaphosphate (CH/PSP) multilayered system to help facilitate thicker growing films with self-extinguishing capability and fewer processing steps. Cotton fabric coated with CH/PSP is rinsed in water baths containing tris(hydroxymethyl)aminomethane [THAM] and compared to control samples rinsed with deionized water. Only 10 bilayers of the CH/PSP system rinsed with THAM are required to achieve self-extinguishing behavior and pass a vertical flame test, while 15 bilayers of the control system are needed to achieve similar results.

膨胀型多层阻燃剂处理中的胺盐增稠

逐层组装通常需要许多沉积步骤才能获得有效阻燃纳米涂层的合适厚度。为了使该技术在工业上更可行，将胺盐添加到壳聚糖/六偏磷酸钠（CH / PSP）多层系统的漂洗步骤中，以帮助促进具有自熄能力和较少加工步骤的较厚生长膜。将涂有CH / PSP的棉织物在含有三（羟甲基）氨基甲烷[THAM]的水浴中漂洗，然后与用去离子水漂洗的对照样品进行比较。用THAM冲洗的CH / PSP系统只有10个双层才能实现自熄性能并通过垂直火焰测试，而控制系统需要15个双层才能达到类似的效果。
