FILTERS AND METHODS OF MAKING AND USING THE SAME

摘要

Filters for removing particulate and gaseous organic and inorganic materials from a fluid stream are disclosed. The filters may contain a polymer matrix and optional sequestering agents. Methods of making filters are also disclosed. Methods of using filters to remove one or more materials from a fluid stream, such as an air stream, are also disclosed. Methods of forming a filter media are also disclosed. In one method, a polymer is selecting for the sorbent system of the filter media based on the diffusion rate of a given analyte into the selected polymer as measured by an optical waveguide interferometer.
