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.

Abstract: Disclosed herein is a porous material comprising a biopolymer functionalized with a carbon dioxide capturing moiety; where the biopolymer is in the form of a foam or an aerogel having a bulk density of 500 grams per cubic meter to 2500 grams per cubic meter. Disclosed herein too is a method comprising functionalizing a biopolymer with a carbon dioxide capturing moiety; dissolving the biopolymer in an aqueous solution to form a first solution; reducing the temperature of the first solution to below the freezing point of the aqueous solution; displacing the aqueous solution with a first solvent that has a lower surface tension than a surface tension of the aqueous solution; and drying the first solvent to produce a porous biopolymer having a bulk density of 500 grams per cubic meter to 2500 grams per cubic meter.

Abstract: A method for producing nanocellulose is described herein. The method includes contacting a cellulosic material with an oxidizing agent, and a compound selected from the group consisting of an alkali metal bromide, an alkali metal iodide, an alkali metal fluoride, an alkali metal chloride, or a combination thereof, in an aqueous solution to provide an oxidized cellulose mixture. The nanocellulose prepared according to the method is also described.
