摘要:
Processes for fabricating selectively permeable laminates are provided. In various embodiments, the laminates are useful for fabrication as a protective article and are substantially impermeable to hazardous chemical and biological agents, but sufficiently permeable to water vapor that, if worn as protective apparel, it is both protective and comfortable to wear.
摘要:
Chitosan films and laminates made from the films are provided. The films and laminates can be used to make a variety of finished articles that can be used to provide protection from hazardous chemical and biological agents.
摘要:
This invention relates to a barrier film useful in protective apparel and structures, and a process for making said film; the film comprising a polyurethane network having a polyalkylamine incorporated therein, wherein the film, after contact with boiling water for 5 minutes, has less than a 50 percent loss in weight of the polyalkylamine.
摘要:
This invention relates to a laminate useful in protective apparel and structures, and processes for making said laminate, the laminate comprising i) a polymer barrier layer comprising a polyurethane network having a polyalkylamine incorporated therein; and ii) a support substrate; wherein the laminate, after contact with boiling water for 5 minutes, has less than a 20 percent loss in weight of the polyalkylamine.
摘要:
This invention relates to a polymer composition useful as a chemical barrier, and films, laminates, and articles comprising the polymer composition and methods for making the polymer composition; the polymer composition comprising: a polyurethane network having a polyalkylamine incorporated therein, wherein the polymer composition, after contact with boiling water for 5 minutes, has less than a 50 percent loss in weight of the polyalkylamine.

摘要:
Protective laminates are provided that include (a) a layer that is breathable and highly impermeable to chemicals to a degree that is subject to reduction upon flexing of the highly impermeable layer alone; and (b) a breathable non-textile layer attached to the highly impermeable layer, the non-textile layer mitigating the reduction in the impermeability of the highly impermeable layer if the laminate is flexed. The laminates may, for example, be attached to textiles and used in protective fabrics.
摘要:
The invention relates to conductive polymer composites comprising a first layer comprising at least one electrically doped conductive polymer and a second layer comprising at least one material selected from a colloid-forming polymeric acid, a salt of a colloid-forming polymeric acid, a non-polymeric fluorinated organic acid, and a salt of a non-polymeric fluorinated organic acid.
摘要:
Compositions, and methods of making, are provided comprising non-aqueous dispersions of at least one doped conductive polymer and at least one colloid-forming polymeric acid, wherein the conductive polymer is selected from a polythiophene, a polypyrrole, a polyaniline, and combinations thereof. Electronic devices and other applications having at least one layer made from at least one such compositions are further provided.
