A composite caulk comprising paper wool, perlite, a particulated wood material having a particle size below 2 mm, a particulated fire retardant bark material having at least one axis of length with a dimension below 2 mm and a polyvinyl-acetate based aqueous dispersion adhesive; and wherein said composite caulk forms a heterogeneous caulk which can be dispensed using a handheld caulking gun.

A method for producing an electrode active coating on a current collector comprising providing isolated lignin and subjecting the isolated lignin to a pre-treatment in order to remove low molecular mass fractions of the lignin. The pre-treated lignin is mixed with an electrode active material, water and a conductive additive material so as obtain a slurry adapted for coating of a current collector. The coating obtained by the method comprises pre-treated lignin as a binder. The coating obtained has good binding properties between the particles of the coating as well as to the current collector. Furthermore, it has excellent electrochemical properties during use in a lithium-ion battery.

Aspects of the disclosure provide coating compositions and methods of use thereof.

A coating, a method for coating surfaces, and the coated surfaces. The method includes providing a substrate with a cleaned metal surface; contacting and coating the metal surface with an aqueous composition having a ph of from 0.5 to 7.0 and in the form of a dispersion and/or a suspension; optionally rinsing the organic coating; and drying and/or baking the organic coating, or optionally drying the organic coating and coating same with a similar or another coating composition thereto. The composition contains a complex fluoride in a quantity of 1.1 10.sup.6 mol/l to 0.30 mol/l based on the cations. An anionic polyelectrolyte in a quantity of 0.01 to 5.0 wt % based on the total mass of the resulting mixture is added to an anionically stabilized dispersion made of film-forming polymers and/or a suspension made of film-forming inorganic particles.

The present invention relates to the field of displays and discloses a polyimide substrate, which is manufactured by reacting lignin, polyimide and a free radical initiator. Because lignin contains various active groups, for example, hydroxyl, carboxyl and aryl, etc., when it is introduced into the polymer structure of polyimide, the maximum absorption peak of the polymer can be made to redshift from less than or equal to 280 nm to less than or equal to 380 nm, so that a certain absorption and screening action may be laid on the light wave during a subsequent Laser Lift Off process, and the substrate and the liquid crystal may be prevented from being damaged during a Laser Lift Off process of the glass base substrate, thereby guaranteeing the display quality of the flexible display.

An oleophilic and hydrophobic nanocellulose material is disclosed herein, for nanocellulose sponges and other applications. The oleophilic and hydrophobic nanocellulose material comprises lignin-coated cellulose nanofibrils and/or lignin-coated cellulose nanocrystals. In various embodiments, the nanocellulose material is in the form of a 2D coating or layer, or a 3D object (e.g., foam or aerogel). The nanocellulose material may be disposed onto a scaffold. A process is provided for producing an oleophilic and hydrophobic nanocellulose object, comprising fractionating a biomass feedstock with an acid, a solvent for lignin, and water, to generate cellulose-rich solids and a lignin-containing liquor; mechanically treating the cellulose-rich solids to form cellulose fibrils and/or cellulose crystals; generating a nanocellulose object from the intermediate nanocellulose material; exposing the nanocellulose object to the lignin-containing liquor to allow lignin to deposit onto a surface of the nanocellulose object; and recovering the oleophilic and hydrophobic nanocellulose object.
