“…The calcination of diatomite was made during 1 h at 1000 C under air [20]. Calcination of diatomite led to an internal sintering [21], entailing a decrease of the porosity and internal surface, and hence of the global surface area. This was confirmed by S BET measurements presented in Table 1.…”

“…The hypothesis is that the first layer made of polyacrylic acid and montmorillonite may produce a "brick and mortar" structure to reduce volatile feed to the gas phase, while providing stability to the remaining portion of the coating (Carosio et al, 2015a). In the second layer, boehmite (BOH) nanoparticles deposited within a poly(diallyldimethylammonium chloride) (PDAC) may release water during combustion (with volatile dilution and cooling effects) while also leaving an inorganic protective layer made of aluminum oxide (Rothon and Hornsby, 2014). The outermost layer made of ammonium polyphosphate (APP) and montmorillonite (MMT) acts as inorganic intumescent layer producing an expanded silicoalluminophosphate barrier .…”

The water-based deposition of flame retardant coatings on flexible polyurethane foams has attracted great interest among the scientific community due to the great performances associated with this technology. Unfortunately, this approach results inefficient as it requires a high number of steps in order to achieve the desired properties. In this paper, we report the production of flame-retardant foams by means of the simple deposition of only three nanoparticles containing layers. The composition and order of the deposited layer has been designed in order to provide specific flame retardant actions, targeting the delayed release of polymer decomposition products to the gas phase, the dilution of these flammable products with water, and the intumescent barrier formation. The morphology of the coated foams after the adsorption of each layer has been investigated by scanning electron microscopy, demonstrating the ability of each adsorbed layer to completely wrap the complex 3D structure of the foam. This three layers-based coating produces a protective exoskeleton that is capable of self-extinguishing the flame in standard flammability tests, leaving the foam almost unaffected (final residue 98%). In forced combustion tests by cone calorimetry, treated foams showed considerably reduced combustion rates, with reduced peak of heat release rate (−50%) as well as consistent reduction in the smoke optical density (−51%) and the total smoke release (−34%). In addition, treated foams have been demonstrated to maintain the ability to self-extinguish the flame as well as reduced combustion rates and smoke production even after being subjected to 100 compression cycles.

“…The successful commercial flame retardants for polymer matrix with effective performance are halogenated flame retardants such as tetrabromobisphenol (TBBPA) 10 , the release of smoke, carbon monoxide and corrosive gases (namely HBr) during the burning results in environmental effect with health hazards [9][10][11] . Furthermore, the alternative flame retardants such as phosphorus and inorganic based, present a significant negative impact on mechanical behaviour which is mainly expressed regarding tensile behaviour, flexural properties and impact properties [12][13][14] .…”

This study investigated the effect of intumescent mats (M1 and M2) with different compositions on the post-fire performance of carbon fibre reinforced composites (CFRP). The sandwich structure was designed for composites where M1 (CFRP-M1) or M2 (CFRP-M2) mats were covered on the composite surface. A significant reduction in the peak heat release rate (PHRR) and total heat release (THR) was observed from the cone calorimetric data and CFRP-M1 composite showed the lowest value of 148 KW/m 2 and 29 MJ/m 2 for PHRR and THR, respectively. Additionally, a minor influence on mechanical properties was observed due to the variation of composite thickness and resin volume in the composite. The post-fire properties of composite were characterised and the M1 mat presented better retention of flexural strength and modulus. The feasibility of two-layer model was confirmed to predict the post-fire performance of composites and reduce the reliance on the large amounts of empirical data.
