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.
