Abstract: A flame retardant composition comprising graphene nanoplatelets and a condensation product of a sulfonated aromatic compound with formaldehyde, wherein the w/w ratio between the graphene and the condensation product is in the range of 1:15 to 4:1. The composition may be in the form of a water dispersion applied to the surface of the article to be treated.The composition has optimal flame retardant properties even when applied in relatively modest quantities.
