Abstract:
A method for the production of a composite material comprising nanofibrillated polysaccharide, the method comprising the following steps: (i) providing a liquid suspension of the nanofibrillated polysaccharide; (ii) bringing said liquid suspension in contact with at least one additive, thereby forming a composite material suspension, wherein the composite comprises the nanofibrillated polysaccharide and the at least one additive, (iii) increasing the solid contents of said composite material suspension, thereby forming a high solid contents composite material suspension.
