- Cellulose fibers were functionalized using the layer-by-layer approach, which allows for the formation of a coating by positively and negatively charged layers of polyelectrolytes on the fiber surface, consisting of sodium hexametaphosphate and chitosan. By using this coating approach, it was possible to obtain a bio-based, homogeneous and flame-retardant coating. Self-extinguishing properties was achieved at 1 bi-layer (BL) as visible in a horizontal flame test, while non-ignitability was obtained after 3BL coating. The coated cellulose fibers were used to produce foams, a self-standing lightweight 3D structure, by freeze-drying. Even though made by mainly cellulose, these foams gave self-extinguishing results when prepared by 1BL coated fibers and non-ignitability when prepared with 3BL coated fibers. Cone calorimetry showed a decrease in heat release rate and total heat release of 56% and 68% respectively for the foam containing 3BL coated fibers.
