Cnf cellular solid material |
| abstract |
The present invention relates to cellular solid materials comprising at least 50 wt% cellulose nanofibers (CNF) and at least 0.2 but less than 40 wt% of a non-ionic surfactant, as calculated on the total weight of the cellular solid material, wherein the material has a density of less than 500 kg/m3; and at least 50% of the cells of the material have a diameter of at least 10 llm. The present invention also relates to a method for preparation of such materials, comprising the steps of providing a dispersion comprising cellulose nanofibers (CNF) in an aqueous solvent; adding a non-ionic surfactant, or a combination thereof to the dispersion to obtain a mixture; preparing a wet foam from the mixture, wherein the wet foam has a density less than 98% of the mixture; and drying the wet foam to obtain a cellular solid material. Moreover, the present invention refers to the use of such materials for insulation, as a packaging material and or as an absorption material. |
