Facile preparation of a hydrophobic intumescent flame retardant toward simultaneously enhanced flame retardancy and smoke suppression of thermoplastic polyurethane

In this work, a hydrophobic intumescent flame retardant (HIFR) based on ammonium polyphosphate (APP), tannic acid (TA), CuO and polydimethylsiloxane (PDMS) was fabricated via an aqueous phase reaction. The surface of the HIFR was coated with spherical CuO nanoparticles and has a water contact angle...
