A multi-functionally modified polymer binder for lithium ion batteries, which is prepared by a free radical graft copolymerization or a Michael addition reaction, with a biomass polymer or a synthetic polymer as a substrate, and a hydrophilic monomer and a lipophilic monomer as functionally modifying monomers. The binder presents a three-dimensional network body with a multi-branch structure, provides more active cites for contacting with the electrode active materials, improves uniformity and flatness in the formation of films from electrode slurry, enhances the binding strength between the electrode active materials, the conductive agents and the current collector, has high elasticity and binding strength, and is applicable in water/organic solvent. Use of the binder in positive electrodes and negative electrodes can facilitate the conduction of electrons/ions during charging and discharging, reduce the electrochemical interface impedance of the electrodes, and largely improve high-rate performances and cycling stabilities of positive and negative electrode materials for lithium batteries. Moreover, raw materials of the binder can be obtained from wide variety of sources, which significantly reduces the cost. Accordingly, the binder has a promising market potential.

The present invention aims to provide a polyrotaxane-containing composition having excellent transparency. The present invention relates to a polyrotaxane-containing composition including: a polyrotaxane that has a cyclic molecule, a linear molecule threading through a cavity of the cyclic molecule in a skewered manner, and capping groups capping both ends of the linear molecule; and an alkyl (meth) acrylate that has a C4-C18 alkyl group, the polyrotaxane having at least one cyclic molecule that has a C4-C18 alkyl group.

Bioderived pressure-sensitive adhesives. The present invention solves ongoing needs for further biofriendly adhesives. The role of mobile cross-links on the properties of a bio-friendly adhesive made using composites of cyclodextrin-based macromolecules and poly(lipoic acid) is demonstrated. Cyclodextrin-based hosts and polyrotaxanes with pendant groups of lipoic acid (a commonly ingested antioxidant) are modified to incorporate them as cross-links in poly(lipoic acid) networks obtained by simple heating in open air. By systematically varying the adhesive formulations while probing their mechanical and adhesive properties, trends in structure-property relationships that enable one to tune network properties and access bio-friendly, high-tack pressure-sensitive adhesives are shown. This invention provides bio-derived adhesive materials that are biofriendly and exhibit adhesion underwater. Multiple applications are possible including a pressure sensitive adhesive, a load bearing adhesive, an underwater adhesive, and adhesives for biomedical applications.
