Claim Text:
1. A composite material for capture and concentration of a species of interest, comprising: a. a substrate; b. a porous composite thin film formed by mixing a porous polymer with a nanostructured material, wherein the porous polymer is present in a range from 5 wt % to about 40 wt % based on the weight of the porous composite thin film, wherein the porous polymer includes strands randomly dispersed within the nanostructured material and binding the nanostructured material, and the substrate is coated by the porous composite thin film, wherein the species of interest is captured and concentrated in the porous composite thin film for trace level detection in air or aqueous environments; c. surface chemistry on the nanostructured particle, wherein the surface chemistry is chemically functionalized prior to inclusion to the porous composite thin film.
