Abstract: A microporous battery separator may be laminated to electrodes and manipulated through manufacturing on a continuous roll of material. Batteries may be constructed by layering the laminated electrodes and separator into various configurations, including flat and wound cell batteries. The separator may or may not contain a nonwoven or other reinforcement, and may be laminated to the electrodes using several different methods.

Abstract: A microporous fire resistant film coated or laminated composite textile may be uses as an upholstery fabric or mattress ticking which provides an air permeable microporous barrier to liquid, allergen or pathogen particle, or biological organism penetration. The microporous cellular structure of the coated or laminated film backing may provide a high capacity reservoir which may contain additives such as antimicrobial, UV absorbing, scent dispersing, or organism repelling particles or other functional agents, while maintaining superior barrier and air permeability properties in the finished product constructions. Applications may include any seating and bedding products where a combination of two or more of the above properties is desired.

Abstract: Bedding products may utilize unique microporous films imparting bidirectional, micro particle and fluid penetration barrier properties, which may or may not contain active ingredient, while maintaining exceptional air permeability. A thin, microporous film with a unique sponge like cellular structure may prevent the migration of dust mites, dust mite feces, other micro particle allergens, pathogens and biological organisms from the interstices of the product to the sleep surface of the product, adversely affecting user health and comfort. Active ingredients such as anti microbial agents, metal oxides, and other materials may be used within the high capacity microporous structure of the film, and may provide customizable functionalities while maintaining barrier performance and superior air permeability. The micro structured film can be applied as a coating or a laminate to mattress or pillow ticking, a foam mattress construction, a comforter, duvet, mattress pad and/or other components of bedding products.

Abstract: A barrier membrane for use in building construction may be manufactured by forming a polymeric film coating on release paper or film; or on nonwoven textiles, paper, fiberglass, or other structural substrate to improve tensile strength. Alternatively, the film may be fully or partially formed and then bonded to a structural substrate. A porous film coating or laminate may be formed using PVDF, PVC, and various polyolefins. A typical membrane may be less than 100 mil thick and greater than 50% porous, and may have a hydrostatic head while retaining gas permeability. Some embodiments may contain active ingredients to combat bacterial or fungal growth, repel insects, or absorb environmental pathogens. The active ingredients may be applied after the porous film is manufactured or may be incorporated during the film manufacturing process.

Abstract: A microporous fire resistant film may be coated or laminated to form a composite textile may be used as a component for various types of apparel. The film may form a vapor permeable barrier that has a hydrostatic head and may repel liquid. The film may form a highly tortuous mechanical barrier to allergens, pathogens, particles, or biological organisms. The film may also serve as a high capacity reservoir for active materials such as antimicrobial materials, UV absorbers, scent dispersers, organism terminating or repelling materials, or other active or passive agents.
