Abstract: A method for manufacturing a suspension of cellulose nanofibrils from an aqueous suspension of cellulose fibres is disclosed including the following steps: chemical treatment, in a reactor, of the aqueous suspension of cellulose fibres by at least one functionalising agent, the chemical treatment being configured to functionalise the cellulose fibres at a modification rate that is higher, indeed strictly higher, than 1.0 mmol/g, and mechanical treatment, in a twin-screw extruder, of the aqueous suspension of functionalised cellulose fibres, each screw of the extruder comprising at least two fibrillation segments. In accordance with at least one embodiment, this method makes it possible to produce a suspension of cellulose nanofibrils of good quality, with a high dry matter content, and while consuming less energy than the methods of the prior art.

Abstract: Disclosed is a method for producing nanocelluloses from a cellulose substrate including cellulose fibers, the method including the following sequence of steps: —a step of enzymatic treatment of the cellulose substrate, by bringing same into contact with at least one cleaving enzyme, then—a step of mechanical treatment of the cellulose substrate subjected to the step of enzymatic treatment, in order to delaminate the cellulose fibres and obtain the nanocelluloses. The at least one cleaving enzyme is chosen from the enzymes belonging to the family of lytic polysaccharide monooxygenases (LPMOs) capable of achieving cleavage in the presence of an electron donor. Also disclosed are the nanocelluloses obtained according to the method.

Abstract: The invention relates to a process for preparing individual cellulose nanocrystals having an electrically conductive coating, said process comprising the steps: reacting non-oxidised glucose units of cellulose with an aryl or heteroaryl compound having an isocyanate group to form a carbamate bond between at least one of the C2, C3 and C6 atoms of the glucose unit and the aryl or heteroaryl compound; polymerising adjacent aryl or heteroaryl compounds bonded to the glucose unit of the cellulose via the carbamate group, such that an electrically conductive structure of these compounds containing aryl or heteroaryl groups is formed.

Abstract: The present invention is aimed to provide carboxymethylcellulose or a salt thereof for a nonaqueous electrolyte secondary battery, an electrode composition containing the same for a nonaqueous electrolyte secondary battery, an electrode for a nonaqueous electrolyte secondary battery, and a nonaqueous electrolyte secondary battery, with a small reduction in the capacity even when charging and discharging are repeated, and with high durability. The carboxymethylcellulose or the salt thereof is used as a binder for an electrode of a nonaqueous electrolyte secondary battery, in which the degree of substitution with carboxymethyl of the carboxymethylcellulose or the salt thereof is 0.5 to 1.5, and a thermal rate of change T that is a difference (WB−WA) between a thermal weight reduction rate WA at a thermal decomposition start point and a thermal weight reduction rate WB at a thermal decomposition end point measured by a thermogravimetric-differential thermal analyzer is 45% or lower.
