Abstract
The invention provides a sorptive sheet material in which finely divided nanocrystalline particles that react with a variety of chemical and/or biological agents are dispersed. The sheet material comprises a fibrous web that is formed of a plurality of fibers that are bonded to each other. The fibrous web contains a relatively high concentration of reactive nanocrystalline particles that are entrapped within the matrix of the fibrous web. Fluids containing toxic agents, such as chemical and/or biological agents, odors and/or odor causing compounds, and toxic industrial compounds, pass into the web and contact the reactive nanocrystalline particles contained therein. The reactive nanocrystalline particles react with, and chemically alter or inactivate the toxic agents. The sorptive sheet material may be used to construct containers, such as remains pouches, for the storing and transporting of contaminated items, particularly human remains.
