Ultra-fast Layer-by-Layer approach for depositing flame retardant coatings on flexible PU foams within seconds / C. F., J. Alongi. - In: ACS APPLIED MATERIALS & INTERFACES. - ISSN 1944-8244. - 8:10(2016), pp. 6315-6319. [10.1021/acsami.6b00598]
Abstract:
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.
