Abstract

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