Effect of NaCl Solution Addition on Improving Some of the Physical Properties of Nylon 6 Solutions used for Electro spinning Purpose

Abstract

Nylon 6 / (0.5, 1, 1.5, 2 and 2.5) wt. % NaCl solutions were prepared for electrospinning technique. The electrical conductivity of polymeric solutionincreases directly with NaCl concentration from 3.8 (mS/ cm) for pure nylon solution to 12.7 mS/cm at nylon 6/ 2.5 wt. % NaCl, and slight decreasing the viscosity and the surface tension of the solution . Increasing the polymeric solution conductivity cause more electrical charges carried by the electrospinning jet. Prepared films morphology tested by SEM and the average fibers diameters measured for each concentration. In this research, it was proved that the nanofibers film shows decreasing the average diameter by increasing NaCl concentration.
