Abstract: An artificial timber comprises the following components in parts by weight: 35-50 parts of cellulose, 20-35 parts of hemicellulose and 15-35 parts of lignin, wherein the artificial timber has a density of 0.01-0.05 g/cm3. The preparing method comprises: (1) dissolving 15-35 parts by weight of lignin, 35-50 parts by weight of cellulose and 20-35 parts by weight of hemicellulose with an ionic liquid; (2) cleaning and replacing it with water to obtain a lignocellulose hydrogel; and (3) drying the lignocellulose hydrogel to obtain an artificial timber. The artificial timber prepared by the present invention is large in specific area, low in density, low in material energy consumption, moderate in condition and easy for operation. The artificial timber obtained by the present invention is regular in shape and is shaped like a sandy beige cylinder without obvious damage and deformation, which indicates that such artificial timber with high specific area has well molding capacity.

Abstract: A composite nanosheet for the cathode of a lithium-sulfur battery, a preparation method thereof, and an electrode and a battery having the same. The composite nanosheet includes carbon nanotubes which are closely accumulated in a two-dimensional plane and are combined together by carbon derived from nanocellulose. Transition metal compound nanoparticles which are uniformly distributed in the nanosheet composite and are fixed by the carbon derived from nanocellulose. Sulfur adsorbed on the surface of the transition metal compound nanoparticles. The composite organically combines and exerts the respective advantages of porous carbon, carbon nanotubes and nano metal oxides/sulfide by designing and constructing the structure of the cathode material.

Abstract: A nanomaterial-biomass fiber composite and preparation method thereof. The biomass fibers are cut or sliced, and then dried. The dried biomass fibers are mixed with a nanomaterial and conveyed to the preheating cylinder of a defibrator for cooking treatment. The cooked mixture is pushed between the grinding discs of the defibrator for hot grinding treatment. The resulting material is then hot pressed to obtain the nanomaterial-biomass fiber composite material. The preparation method benefits from simple operation, low cost, low energy consumption, suitability for industrialized production, and wide application prospect in the field of production of binderless fiberboard.
