Sustainable Halogen-Free Flame-Retardant Flexible Polyurethane Foams via Lignin-Waterborne Polyurethane Pickering Foam Templates.
This study presents a sustainable strategy to fabricate flame-retardant flexible polyurethane foam (FPUF) via a green aqueous Pickering foam templating method. Lignin was used as a biobased stabilizer and gelation agent, while 10-(2,5-dihydroxyphenyl)-10H-9-oxa-10-phosphaphenanthrene 10-oxide (DOPO-HQ) served as a halo...
