At present, environmentally friendly biobased flexible films are of particular interest as next-generation fireproof packaging and sensor materials. To reduce the moisture uptake fire risks induced by hygroscopic flammable films, we report a simple green approach to develop hydrophobic, flame-retardant composite film with synergetic benefit from soy protein isolate (SPI), sisal cellulose microcrystals (MSF-g-COOH), graphene nanosheets (GN), citric acid (CA). Compared SPI/MSF-g-COOH as-prepared SPI/MSF-g-COOH/CA/GN have significantly improved water resistance can maintain excellent physical structure good electrical conductivity in an ethanol flame. This work opens pathway for development novel fire-retardant alarm biosensors.
