This research involves fabricating nanoparticle-filled thin coatings as an innovative approach to reduce the flammability of polyurethane foam typically used in residential home furnishings.  The coatings are typically constructed of four oppositely charged bi- or tri-layers, are 350 nm thick, and contain 50 mass-% carbon nanofibers, multi-walled carbon nanotubes, or sodium montmorillonite clay.  Compared to 17 commercial foam fire retardants, these nanoparticle fire retardant (nanoFR) coatings are 300-1100% more effective at reducing the heat generated from the highly flammable foam.  In a real fire, the impact may be even greater as these nanoFR coatings prevent the foam from generating flaming melt drips, which are responsible for pool fires and significant fire spread.  Additionally, these coatings appear durable when exposed to simulated wear and tear and chewing conditions releasing nanoFRs in the range of a few milligrams per simulated year.
