Abstract: The present disclosure provides adhesive articles that can be removed from surfaces without damage by having reduced or eliminated contribution of a core backing to peel force generated by the adhesive during removal. In some instances, this can be accomplished by a core that loses structural integrity in a direction normal to a plane defined by a major surface. In other instances, the contribution is reduced by compromising the interface between the core and a peelable adhesive layer.

Abstract: The present disclosure relates to porous electrodes and electrochemical cells and liquid flow batteries produced therefrom. The disclosure further provides methods of making electrodes. The porous electrodes include polymer, e.g. non-electrically conductive polymer particulate fiber, and an electrically conductive carbon particulate. The non-electrically conductive, polymer particulate fibers may be in the form of a first porous substrate, wherein the first porous substrate is at least one of a woven or nonwoven paper, felt, mat and cloth. The porous electrode may have an electrical resistivity of less than about 100000 μOhm·m. The porous electrode may have a thickness from about 10 microns to about 1000 microns. Electrochemical cells and liquid flow batteries may be produced from the porous electrodes of the present disclosure.

Abstract: Films and articles are described comprising a microstructured surface having an array of peak structures and adjacent valleys. For improved cleanability, the valleys preferably have a maximum width ranging from 10 microns to 250 microns and the peak structures have a side wall angle greater than 10 degrees. The peak structures may comprise two or more facets such as in the case of a linear array of prisms or an array of cube-corners elements. The facets form continuous or semi-continuous surfaces in the same direction. The valleys typically lack intersecting walls. Also described are methods of making and methods of use. The microstructured surface of the article can be prepared by various microreplication techniques such as coating, injection molding, embossing, laser etching, extrusion, casting and curing a polymerizable resin; and bonding microstructured film to a surface or article with an adhesive.
