Provided herein are color protectant compositions for dyed human hair, and methods for determining the same.

The present disclosure relates to a composition for forming a polyurethane film, a polyurethane film derived from the composition and an article comprising a substrate and the polyurethane film, and the composition for forming a polyurethane film comprises an OH group-containing polymer; a curing agent; and an amphoteric ion-based polymer.

An adhesive composition comprising a polyurethane and a cationic polymeric dopant or a polymerizable cationic dopant may be used to form one or more adhesive layers of electro-optic assemblies. They enable improved electro-optic performance of the corresponding; electro-optic devices even at low temperatures.

An anti-fouling coating is provided, containing a continuous matrix comprising a first component; a plurality of inclusions comprising a second component, wherein the first component is a low-surface-energy polymer having a surface energy, and the second component is a hygroscopic material containing one or more ionic species. The low-surface-energy polymer and the hygroscopic material are chemically connected ionically or covalently, such as in a segmented copolymer composition comprising fluoropolymer soft segments and ionic species contained within the soft segments. The continuous matrix and the inclusions form a lubricating surface layer in the presence of humidity. Coefficient-of-friction experimental data is presented for various sample coatings. The incorporation of ionic species into the polymer chain backbone increases the hygroscopic behavior of the overall structure. Improvement in lubrication enables material to be cleared from a surface using the natural motion of an automotive or aerospace vehicle.

Durable antibacterial coatings are prepared by inter-diffusing zwitterionic polyurethane in acrylic polyurethane. Bacterial attachment is substantially eliminated from the surface of the coatings due to the hydrophilicity of the zwitterionic polyurethane. Long-term antibacterial properties were observed for both Gram-negative and Gram-positive bacteria even when the coatings were constantly challenged by mechanical abrasion.

Provided herein are color protectant compositions for dyed human hair, and methods for determining the same.

Electro-optic assemblies and related materials (e.g., adhesive) for use therein are generally provided. The electro-optic assembly comprises a hybrid adhesive layer comprising two or more adhesive materials including a polyurethane adhesive material and a polyacrylate adhesive material. The polyurethane adhesive material includes an end-capping cyclic carbonate. In some embodiments, the adhesive layer is formed by curing the two adhesive materials under two different sets of conditions, comprising two or more curing steps.

Provided herein are polymers having a polymer backbone including a zwitterionic precursor monomeric unit having a secondary or tertiary amine in the polymer backbone, as well as methods of making and using the same.
