Intumescent All‐Polymer Multilayer Nanocoating Capable of Extinguishing Flame on Fabric

Abstract

An intumescent nanocoating composed of poly(allylamine) and poly(sodium phosphate) is deposited layer-by-layer on cotton fabric. Fire is extinguished right after ignition on the fabric during vertical flame testing. The individual fibers are conformally coated and bubbles form on the fiber surfaces during burning, which is due to an intumescent effect.
