Abstract
The relationship between processing conditions, structure and morphology are key issues
to understanding the final properties of materials. For instance, in the case of polymers to be
used as scaffolds in tissue engineering, wound dressings and membranes, morphology tuning is
essential to control mechanical and wettability behaviors. In this work, the relationship between
the processing conditions of the solution blow spinning process (SBS) used to prepare nonwoven
mats of polyethylene oxide (PEO), and the structure and morphology of the resulting materials are
studied 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 and
polymer concentration), the effect of the solvent composition has been considered. The structure and
morphology of the blow spun fibers are studied as well as their thermal, mechanical behaviors and
dissolution in water. We demonstrate that the morphology of the fibers (size and porosity) changes
with the solvent composition, which is reflected in different thermal and mechanical responses and in
the dissolution rates of the materials in water.
