Poly(acrylic acid)/clay thin films assembled by layer - by - layer deposition for improving the flame retardancy properties of cotton / Guobo Huang in Industrial & engineering chemistry research, Vol. 51 N° 38 (Septembre 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 38 (Septembre 2012) . - pp. 12299-12309 Titre : Poly(acrylic acid)/clay thin films assembled by layer - by - layer deposition for improving the flame retardancy properties of cotton Type de document : texte imprimé Auteurs : Guobo Huang, Auteur ; Huading Liang, Auteur ; Xu Wang, Auteur Année de publication : 2012 Article en page(s) : pp. 12299-12309 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Flame  Thin  film Résumé : A flame-retardant poly(acrylic acid) (FR-PAA) was prepared by copolymerization of N-(2-(5,5-dimethyl-1,3,2- dioxaphosphinyl-2-ylamino)-ethylacetamide-2-propenyl acid (DPEPA) and acrylic acid and used to fabricate various FR-PAA/ montmorillonite (MMT) thin films via layer-by-layer (LbL) deposition as a flame-retardant coating system for cotton fabric. Thermogravimetric analysis (TGA) indicated that treatment of FR-PAA/MMT thin films improved the thermal stability of cotton fabric. Cone calorimeter testing showed that the cotton fabrics coated with the FR-PAA/MMT thin films had less flammability with lower peak heat release rate (PHRR), lower total heat release (THR), and lower average mass loss rate (AMLR). In addition, scanning electronic microscopy (SEM) demonstrated that the surface of the fabrics coated with FR-PAA/ MMT films after combustion was covered by a layer of continuous and compact char.

Thin films of intumescent flame retardant - polyacrylamide and exfoliated graphene oxide fabricated via layer - by - layer assembly for improving flame retardant properties of cotton fabric / Guobo Huang in Industrial & engineering chemistry research, Vol. 51 N° 38 (Septembre 2012)

Higher hydrophobe DPAA content of IFR-PAM results in much thicker assemblies due to hydrophobic association. The results from X-ray diffraction (XRD), atomic force microscopy (AFM), and scanning electronic microscopy (SEM) indicate that the IFR-PAM/ GO ultrathin films with high homogeneity and orientation are formed by LbL assembly driven by hydrogen interaction. The thermogravimetric analysis (TGA) results indicate that the IFR-PAM/GO coating improves the thermal stability of cotton fabric. Cone calorimeter testing shows that the IFR-PAM/GO-coated fabrics become less flammable with lower peak heat release rate (PHRR) and longer time to ignition (TTI). SEM images demonstrate that the surface of the IFR-PAM/GO-coated fabrics is covered by a layer of continuous and compact char after combustion.
