Abstract:
The present invention relates to a method for preparing a surface-treated fibrous material comprising phosphorylated nanocellulose, in which a fibrous material is surface treated with a solution comprising at least one multivalent metal ion followed by drying and post- curing to improve the barrier properties of the material. Fibrous materials as such are also provided.
