4results about "Dextran adhesives" patented technology

The present application provides a binder and a preparation method thereof. The binder comprises a copolymer comprising a building block (I) and a building block (II), wherein the building block (I) is formed by copolymerizing a building block (i) and a building block (ii). The binder of the present application is a multifunctional binder with excellent binding, dispersing and thickening properties. An electrode sheet prepared from the binder of the present application has a relatively low electrode sheet resistance. A secondary battery prepared from the binder of the present application also has excellent cycling performance.

A biocompatible adhesive material is provided for use with living tissue and / or medical implants and the like, as well as methods and kits for making and using the biocompatible adhesive material. The biocompatible adhesive material includes a functionalized poloxamer component and an oxidized polysaccharide component, and can be tailored for specific tissue types and conditions.

This invention relates to the field of paper processing technology, specifically to an aging-resistant polysaccharide-based adhesive, its preparation method and application, and a method for repairing paper tears. The aging-resistant polysaccharide-based adhesive provided by this invention comprises β-1,3-glucan, galactomannan, xylan, calcium carbonate, natural polysaccharide additives, and water; the pH value of the aging-resistant polysaccharide-based adhesive is 7-8.5. The components of the aging-resistant polysaccharide-based adhesive provided by this invention work synergistically, exhibiting good adhesion to both smooth cuts and tears in paper. Furthermore, the tensile strength after bonding is further increased after accelerated aging treatment, demonstrating excellent aging resistance. In addition, the adhesive also has a certain deacidification ability and does not contain organic solvents or synthetic polymers, making it particularly suitable for repairing tears in paper artifacts.
