Determination of the parameters affecting electrospun chitosan fiber size distribution and morphology

► The processing conditions of chitosan electrospun mats are investigated. ► The conditions for obtaining reproducible mats with uniform fibers are presented. ► Fiber diameter is affected by the solution and the distance to the collector. ► Needle diameter and feed rate do not have influence in the chitosan mats. ► Electrospinning does not influence the degree of deacetylation of the polymer.
