AB : In the last few years, electrospinning has proved to be one of the best methods for obtainingmembranes of a micro and nanometric fiber size. This method mainly consists in the spinningof a polymeric or biopolymeric solution in solvents, promoted by the difference in the electricfield between the needle and collector, which is finally deposited as a conjunction of randomlyoriented fibers. The present work focuses on using cellulose derivatives (namely cellulose acetateand ethylcellulose), based on the revaluation of these byproducts and waste products of biorefinery,to produce nanostructured nanofiber through electrospinning with the objective of establishing arelation between the initial solutions and the nanostructures obtained. In this sense, a completecharacterization of the biopolymeric solutions (physicochemical and rheological properties) andthe resulting nanostructures (microstructural and thermal properties) was carried out. Therefore,solutions with different concentrations (5, 10, 15, and 20 wt%) of the two cellulose derivatives anddifferent solvents with several proportions between them were used to establish their influence onthe properties of the resulting nanostructures. The results show that the solutions with 10 wt% inacetic acid/H2O and 15 wt% in acetone/N,N-dimethylformamide of cellulose acetate and 5 wt% ofethylcellulose in acetone/N,N-dimethylformamide, exhibited the best properties, both in the solutionand nanostructure state
