Fabrication of ultrafine fibres from fluoroplastic by electrospinning. Rheological analysis of spinning solutions

The possibility of implementing stable electrospinning and fabricating nonwoven material with fibre sizes in the nano and micron range from P-42 fluoroplastic was demonstrated. The rheological properties of solutions of fluoroplastics in ethyl acetate were investigated. The optimum electrospinning process parameters were determined: conductivity, electric field strength, volumetric flow. It was found that the fibre diameter is most dependent on the volumetric flow and initial viscosity of the polymer solution.
