AB The relationship between processing conditions, structure and morphology are key issuesto understanding the final properties of materials. For instance, in the case of polymers to beused as scaffolds in tissue engineering, wound dressings and membranes, morphology tuning isessential to control mechanical and wettability behaviors. In this work, the relationship betweenthe processing conditions of the solution blow spinning process (SBS) used to prepare nonwovenmats of polyethylene oxide (PEO), and the structure and morphology of the resulting materials arestudied systematically, to account for the thermal and mechanical behaviors and dissolution in water.After finding the optimal SBS processing conditions (air pressure, feed rate, working distance andpolymer concentration), the effect of the solvent composition has been considered. The structure andmorphology of the blow spun fibers are studied as well as their thermal, mechanical behaviors anddissolution in water. We demonstrate that the morphology of the fibers (size and porosity) changeswith the solvent composition, which is reflected in different thermal and mechanical responses and inthe dissolution rates of the materials in water.
