Abstract

Embodiments of the present disclosure pertain to conductive textiles that include a textile component with a plurality of fibers; and metal-organic frameworks associated with the fibers of the textile component in the form of a conductive network. Metal-organic frameworks may have a two-dimensional structure and a crystalline form. Metal-organic frameworks may be conformally coated on the fibers of the textile component. Additional embodiments of the present disclosure pertain to methods of sensing an analyte in a sample by exposing the sample to a conductive textile; and detecting the presence or absence of the analyte by detecting a change in a property of the conductive textile, and correlating the change in the property to the presence or absence of the analyte. The analyte in the sample may reversibly associate with the conductive textile. The association may also result in filtration, pre-concentration, and capture of the analyte by the conductive textile.

First claim

What is claimed is:

1. A method of sensing an analyte in a sample, said method comprising:
exposing the sample to a conductive textile,
wherein the conductive textile comprises:
a textile component comprising a plurality of fibers and a plurality of pores, and
metal-organic frameworks associated with the fibers of the textile component,
wherein the metal-organic frameworks comprise one or more metals and one or more organic ligands coordinated with the one or more metals, and
wherein the metal-organic frameworks are in the form of a conductive network comprising a two-dimensional crystalline lattice; and

detecting the presence or absence of the analyte from the sample, wherein the detecting comprises:
detecting a change in a property of the conductive textile, and
correlating the change in the property to the presence or absence of the analyte.

2. The method of claim 1 , wherein the change in the property of the conductive textile comprises a change in normalized conductance over time (ΔG/Go).

3. The method of claim 1 , wherein the sample is derived from a gaseous environment.

4. The method of claim 1 , wherein the analyte is selected from the group consisting of gases, ketones, alcohols, aromatic compounds, water, neurotransmitters, hormones, proteins, sugars, metal ions, NO, CO, H 2 S, NH 3 , H 2 O, and combinations thereof.

5. The method of claim 1 , wherein the analyte comprises one or more gases selected from the group consisting of NO, CO, H 2 S, NH 3 , H 2 O, and combinations thereof.

6. The method of claim 1 , wherein the exposing comprises flowing the sample through the conductive textile.

7. The method of claim 1 , wherein the exposing comprises incubating the sample with the conductive textile.

8. The method of claim 1 , wherein the exposing results in the reversible association of any analyte in the sample with the conductive textile.

9. The method of claim 8 , wherein the association also results in filtration, pre-concentration, and capture of the analyte by the conductive textile.

10. The method of claim 1 , wherein the analytes are detected at concentrations of less than about 100 ppm.

11. The method of claim 1 , wherein the detecting comprises detecting a plurality of analytes.

12. The method of claim 1 , wherein the detecting occurs in a humid environment, and wherein the humid environment has a relative humidity of 15% or higher.

13. The method of claim 1 , further comprising a step of releasing the analyte from the conductive textile.

14. The method of claim 13 , wherein the releasing occurs by washing the conductive textile.
