Abstract
A solution is provided comprising boron nitride nanotubes (BNNTs) in a liquid solvent. An optical waveguide, such as an optical fiber, is contacted with the solution so as to form a layer of the solution supported on at least a portion of the optical waveguide. The liquid solvent is then removed from the layer of the solution supported on the optical waveguide in order to form a coating of the BNNTs on the optical waveguide. Further provided is a BNNT coated optical waveguide for use as a sensor.
Claims55
A method for coating at least a portion of an optical waveguide with boron nitride nanotubes (BNNTs), the method comprising:
- providing a solution comprising BNNTs in a liquid solvent;
- contacting at least a portion of an optical waveguide with the solution so as to form a layer of the solution supported on the optical waveguide;
- and
- at least partially removing the liquid solvent from the layer of the solution supported on the optical waveguide, thereby forming a coating of the BNNTs on a surface of the optical waveguide.
