Preparation of polysulfoneamide electrospinning nanofibers

Abstract

In this paper, we select electrospinning technique to fabricate polysulfonamide nanofibers. Polysulfonamide with relatively high inherent viscosity was prepared based on 4,4'-diaminodiphenylsulfone and terephthaloyl chloride in the common solvent N,N-Dimethylacetamide (DMAc) by the method of low-temperature solution condensation polymerization. Our research work focused on studying the effect of concentration of solution, processing parameters including voltage and distance from tip to collector on the spinnability of the solution and morphology electrospun polysulfonamid fibers. The microstructures of the electrospun polysulfonamid fibers were quantitively investigated by scanning electron microscope (SEM) as a function of processing variables.
