Abstract



Graphene, as a two-dimensional nanomaterial with a unique structure, is currently widely used in the field of fire retardancy. In this study, cellulose molecules were used as the scaffold material, and a freeze-drying method was employed to synthesize fire-resistant graphene aerogels with anisotropic structures. A combined approach of experimental analysis and molecular dynamics simulations was used to comprehensively elucidate the fire-retardant mechanism of these graphene aerogels. This composite material exhibits excellent compression strength and stiffness, a low thermal conductivity (0.06 W/(mK)), and a significant improvement in fire-retardant performance (a decrease of 88.6% in peak heat release rate compared to cellulose aerogels).
