Abstract: A modified kraft pulp fiber with unique properties is provided. The modified fiber can be a modified bleached kraft fiber that is almost indistinguishable from its conventional counterpart, except that it has a low degree of polymerization (DP). Methods for making the modified fiber and products made from it are also provided. The method can be a one step acidic, iron catalyzed peroxide treatment process that can be incorporated into a single stage of a multi-stage bleaching process. The products can be chemical cellulose feedstocks, microcrystalline cellulose feedstocks, fluff pulps and products made from them.

Abstract: Methods for producing dissolving grade pulp and microcrystalline cellulose from tobacco are provided. The methods include chemical pulping a tobacco input to form a tobacco pulp. Chemical pulping the tobacco input includes combining the tobacco input with a strong base defining a weight from about 5% to about 50% of the tobacco input, and heating the tobacco input and the strong base with an H-factor from about 500 to about 3,300. Further, the methods include bleaching the tobacco pulp to produce a dissolving grade pulp. Bleaching the tobacco pulp may include chlorination of the tobacco pulp with a chlorine dioxide solution, and caustic extraction of the tobacco pulp with a second strong base. A related tobacco-derived microcrystalline cellulose product is also provided, which can be used as a binder, a filler, and/or a texturizer in a tobacco product, such as a smokeless tobacco product.

Abstract: A method is provided for preparing electrically conductive polymer and cellulose nanocomposite particles and nanocomposite materials. Cellulose microparticles coated with a conductive polymer are added to an acid solution for initiating an acid hydrolysis reaction for a prescribed time interval to form conductive polymer coated cellulose nanoparticles. After quenching the acid hydrolysis reaction, the nanoparticles are separated to obtain a colloidal solution of conductive nanoparticles. The conductive nanoparticles may be subsequently formed into a solid nanocomposite material such as a conductive film. Transparent conductive films may be prepared by forming thin layers having a thickness on a micron or submicron scale.
