Abstract
The present disclosure relates to cellulose nanomaterials made or derived from tobacco and methods for the production thereof. The tobacco-derived cellulose nanomaterials can be employed in various industrial applications such as film forming applications and solution thickening technologies. In particular, the disclosure is directed to methods for preparing tobacco-derived cellulose nanomaterials using less fibrillation cycles than in the production of wood pulp. The invention includes a method for preparing tobacco derived nanocellulose material comprising receiving a tobacco pulp in a dilute form such that the tobacco pulp is a tobacco pulp suspension with a consistency of less than about 5%; and mechanically fibrillating the tobacco pulp suspension to generate a tobacco derived nanocellulose material having at least one average particle size dimension in the range of about 1 nm to about 100 nm.
