The Mechanical Properties of PVC Nanofiber Mats Obtained by Electrospinning

This paper investigates the mechanical properties of oriented polyvinyl chloride (PVC) nanofiber mats, which, were obtained by electrospinning a PVC solution. was dissolved in solvent mixture tetrahydrofuran/dimethylformamide. Electrospinning parameters used our work were, voltage 20 kV; flow rate 0.5 mL/h; distance between syringe tip and collector 15 cm. The rotating speed drum varied from 500 to 2500 rpm with range rpm. Nanofiber mats characterized scanning electron microscope, thermogravimetric analysis, differential calorimetry methods. such as tensile strength, Young’s modulus, thermal degradation, glass transition temperature also analyzed. It shown that, increasing collector’s rotation 0 (flat plate collector) (drum collector), average diameter nanofibers decreased 313 ± 52 229 47 nm. At same time, it observed that resulting improved: strength increased 2.2 0.2 MPa 9.1 0.3 MPa, modulus 53 14 308 19 MPa. Thermogravimetric analysis measurements showed there no difference process degradation powders. On other hand, powders did show different values, values 77.5 °C 83.2 °C, respectively.
