Beschreibung
Zusammenfassung:	An ultra-lightweight, open-pore foamed cellulose material with an increased surface area, having ion exchangeable functional groups introduced in it. The cellulose material presents a three-dimensional network structure which, upon swollen, has a pore diameter of 0.5 to 12.0 mm, a mean pore diameter of 0.1 to 1.7 mm, a specific surface area of 1.0 to 10.0 m /g, a true density of 1.4 to 1.6 g/cm and a porosity of 90 % or greater. The ion exchangeable functional groups, for instance, may be cationic polyethyleneimine.
