Abstract: A method for producing carbon nanotube sheets is provided. The method may include steps of: dispersing carbon nanotubes and cellulose in a solvent to form a slurry, stirring the slurry, and depositing the slurry onto a substrate using a coating method to form a carbon nanotube sheet. The carbon nanotube sheet may include 0.1 wt. % to about 95 wt. % cellulose relative to the total weight of the carbon nanotube sheet and may have an emissivity of about 0.05 to about 0.3. The carbon nanotube sheet may be utilized to provide infrared shielding to a surface.

Abstract: A contact lens may include a lens comprising a hydrogel configured to be worn on an eyeball. A contact lens may include an electronic component fully encapsuled within the lens, wherein the electronic component may include a sensor, a battery, a supercapacitor, an electronically controlled microfluidic channel, or combinations thereof. Methods for producing such a contact lens are also disclosed.

Abstract: A composition for manufacturing an electrode, the composition including an electrically conductive carbon-based compound, at least one species able to form a catalyst, and cellulose microfibrils encapsulating chitosan. The cellulose microfibrils create a fibrous mesh binding the composition while limiting coating of the catalyst. Thus, the catalyst remains accessible to the surrounding environment, to allow the redox reactions at the electrode. The electrochemical performances of the electrode are consequently improved. The composition is furthermore particularly adapted for shaping an electrode by 3D printing.

Abstract: The present disclosure describes methods of producing superhydrophobic carbon nanotube sheets. The methods disclosed herein allow the rapid and scalable production of superhydrophobic carbon nanotube sheets that may remain on a substrate, or they may be removed from the substrate to produce freestanding superhydrophobic carbon nanotube sheets. The carbon nanotube sheets produced by the present methods were confirmed to be superhydrophobic by water droplet contact angle.
