: In the last few years, electrospinning has proved to be one of the best methods for obtaining
membranes of a micro and nanometric fiber size. This method mainly consists in the spinning
of a polymeric or biopolymeric solution in solvents, promoted by the difference in the electric
field between the needle and collector, which is finally deposited as a conjunction of randomly
oriented fibers. The present work focuses on using cellulose derivatives (namely cellulose acetate
and ethylcellulose), based on the revaluation of these byproducts and waste products of biorefinery,
to produce nanostructured nanofiber through electrospinning with the objective of establishing a
relation between the initial solutions and the nanostructures obtained. In this sense, a complete
characterization of the biopolymeric solutions (physicochemical and rheological properties) and
the 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 and
different solvents with several proportions between them were used to establish their influence on
the properties of the resulting nanostructures. The results show that the solutions with 10 wt% in
acetic acid/H2O and 15 wt% in acetone/N,N-dimethylformamide of cellulose acetate and 5 wt% of
ethylcellulose in acetone/N,N-dimethylformamide, exhibited the best properties, both in the solution
and nanostructure state
