Solvent system for steady state electrospinning of polyamide 6.6

A mixture of formic acid/acetic acid makes it possible to electrospin polyamide 6.6 in steady state conditions. Steady state conditions are essential in nozzle electrospinning to generate a stable process which fabricates reproducible material, permitting industrial upscaling. This study shows that...

Description
Summary:A mixture of formic acid/acetic acid makes it possible to electrospin polyamide 6.6 in steady state conditions. Steady state conditions are essential in nozzle electrospinning to generate a stable process which fabricates reproducible material, permitting industrial upscaling. This study shows that only a limited mixture range of formic acid/acetic acid allows electrospinning of polyamide 6.6 in steady state.Furthermore, the weight concentration in solution; the tip to collector distance and the flow rate have been changed to control the average diameter of the nanofibres. The average diameter increases by increasing weight concentration in solution, increasing volume fraction of acetic acid in the mixture, increasing tip to collector distance and increasing flow rate.
