Abstract
An anti-fogging composition is described herein. The composition includes a nanocellulose comprising cellulose nanofibrils, cellulose nanocrystals, or a combination thereof, and water. A method of preparing an anti-fogging coating includes applying the anti-fogging composition to at least a portion of a surface of a substrate to form a coating. An article including a coating formed from the anti-fogging composition is also disclosed. Coatings prepared from the anti-fogging compositions are water proof, and offer a cost-effective alternative to other anti-fogging coatings.
Claims15
A method of preventing fog on a surface, the method comprising:
- applying an anti-fogging composition to the surface,
- wherein the anti-fogging composition comprises
- a nanocellulose comprising cellulose nanofibrils, cellulose nanocrystals, or a combination thereof;
- a surfactant:
- a water-soluble polymer;
- and
- water;
- and
- removing at least a portion of the water from the surface to provide a coating disposed on at least a portion of the surface, wherein the coating has a thickness of 100 nanometers to 2 micrometers.
