Abstract: Articles that contain a solid support with a grafted chain extending from the solid support, methods of making these articles, and various uses of the articles are described. More specifically, the grafted chain has a functional group that can react with or interact with target compound. Alternatively, the functional group on the grafted chain can react with a modifying agent to provide another group that can react with or interact with the target compound. The grafted chains are attached to the solid support through a ring-opened azlactone group. The articles can be used to purify the target compound or to separate the target compound from other molecules in a sample.

Abstract: A polymer matrix composite comprising a porous polymeric network; and a plurality of functional particles distributed within the polymeric network structure, and wherein the polymer matrix composite has an air flow resistance at 25° C., as measured by the “Air Flow Resistance Test,” of less than 300 seconds/50 cm3/500 micrometers; and wherein the polymer matrix composite has a density of at least 0.3 g/cm3; and methods for making the same. The polymer matrix composites are useful, for example, as filters.

Abstract: Film forming gel compositions, useful in creating conformable and flexible gel bandages, can be formulate from a film-forming polymer, a tackifier, and a volatile solvent. The film forming gels can also include antiseptics, cationic polymer coagulants, fillers, and other additives. The gel compositions form relatively thick films when dried on tissue, and can exhibit enhanced breathability to promote wound healing.

Abstract: A coalescing element for aggregating droplets of an emulsion. The coalescing element includes a nonwoven web substrate. A coalescer that includes the coalescing element can also include a housing and a fluid inlet and a fluid outlet each in fluid communication with the coalescing element. The coalescing element and coalescer may be useful for emulsions that form in solvent extraction/electrowinning copper processing and for other emulsions.

Abstract: A wipe article includes a substrate, a cationic coating disposed on a surface of the substrate, distributed throughout the substrate, or both. The cationic coating contains a guanidinyl-containing polymer that is crosslinked and bound to the substrate. The substrate includes sponge, nonwoven fabric, or woven fabric. The wipes are useful for removing microorganisms from a microorganism-contaminated surface and also for reducing re-contamination of the cleaned surface or transfer to another surface of the removed microorganisms.
