Abstract

Provided are textiles comprising one or both of MXene-coated fibers and MXene-coated yarns. The textiles are conductive, electroactive, and the fibers and yarns exhibit favorable mechanical and electrical properties, and can be incorporated into a variety of devices and uses.

First claim

1 . A conductive fiber, comprising:
a substrate fiber, the substrate fiber defining an outer surface coated with a first plurality of MXene particulates.

2 . The conductive fiber of claim 1 , wherein the substrate fiber comprises a naturally occurring material.

3 . The conductive fiber of claim 1 , wherein the substrate fiber comprises a synthetic material.

4 . The conductive fiber of claim 1 , wherein the first plurality of MXene particulates has an average particle size in the range of from about 100 to about 1000 nm.

5 . The conductive fiber of claim 1 , wherein the first plurality of MXene particulates comprises two different MXene materials.

6 . The conductive fiber of claim 1 , wherein the first plurality of MXene particulates defines a unimodal particle size distribution.

7 . The conductive fiber of claim 1 , wherein the first plurality of MXene particulates defines a multimodal particle size distribution.

8 . The conductive fiber of claim 1 , wherein the first plurality of MXene particulates are attached to the substrate fiber by electrostatic interaction.

9 . A yarn, comprising:
a plurality of conductive fibers according to claim 1 .

10 . The yarn of claim 9 , the yarn defining an outer surface coated with a second plurality of MXene particulates.

11 . The yarn of claim 10 , wherein the second plurality of MXene particulates has an average particle size in the range of from about 500 to about 15,000 nm.

12 . The yarn of claim 10 , wherein the second plurality of MXene particulates comprises two different MXene materials.

13 . (canceled)

14 . (canceled)

15 . The yarn of claim 10 , wherein the second plurality of MXene particulates are attached to the outer surface of the yarn by electrostatic interaction.

16 . The yarn of claim 9 , wherein the yarn is characterized as having a MXene loading of from about 0.1 to about 2.0 mg/cm, wherein the yarn is characterized as having a MXene mass loading of from about 10 to about 75 wt %, wherein the yarn is characterized as having a conductivity of from about 30 to about 150 S/cm, wherein the yarn is characterized as having a conductivity of from about 30 to about 150 S/cm, or any combination thereof.

17 . (canceled)

18 . (canceled)

19 . The yarn of claim 10 , wherein the yarn is characterized as having a MXene loading of from about 2.0 to about 3.0 mg/cm, wherein the yarn is characterized as having a MXene mass loading of from about 75 to about 85 wt %, wherein the yarn is characterized as having a conductivity of from about 200 to about 440 S/cm, or any combination thereof.

20 . (canceled)
