摘要： Methods for integrating the production of carboxylated CNCs and carboxylated CNFs from cellulose are provided. Carboxylated CNCs, carboxylated cellulosic solid residues (CSRs) in the form of cellulose fibers (CF) and/or cellulose microfibrils (CMFs), and carboxylated CNFs fabricated using the methods are also provided. The methods are based on the acid hydrolysis of a cellulosic material using weak solid organic acids to produce carboxylated CNCs and CNFs with thermal stabilities that are higher than the thermal stabilities of the cellulosic materials from which they are derived.

摘要： A defibrating unit includes a rotating unit and a fixing unit. The rotating unit and the fixing unit are arranged so as to be apart from each other with a gap therebetween in an intersecting direction that intersects with a rotating shaft of the rotating unit. The rotating unit includes a surface that stands up along an axial direction of the rotating shaft and that is arranged on a side section in the axial direction and arranged at a side where a defibration object is introduced. The fixing unit includes a plurality of plates that are layered in the axial direction, and the plates has a plurality of convexities that protrude at a side facing the rotating unit.

摘要： A sheet manufacturing apparatus includes a defibrating unit and a sheet forming unit. The defibrating unit includes a rotating unit and a housing, and is configured to carry out a dry-type defibrating process by rotating the rotating unit. The housing includes a cover portion and a fixing unit attached to the cover portion and spaced apart from the rotating unit in a direction perpendicular to an axial direction of the rotating unit so as to form a gap between the rotating unit and the fixing unit. The sheet forming unit is configured to form a sheet by accumulating defibrated material. The rotating unit includes a rotor having protruding sections on an outer circumference of the rotor, and a feeding blade arranged on a side section of the rotor on a side of an input section for the defibration object and configured to generate a flow of air.
