Özet

The aim of the study is to produce nanofibers using electrospinning with aqueous poly(vinyl alcohol)(

PVA) solutions. Effect of PVA molar mass and concentration and effect of surfactants on the properties

of PVA solutions and on the diameter size of electrospun PVA nanofibers were examined. It was

shown that the viscosity of the polymer solution was increased by increasing PVA molar mass and concentration.

To obtain the nanofiber structure, optimum PVA18.000 (molar mass = 18,000 g/mol) and PVA50.000

(molar mass = 50,000 g/mol) concentrations were found to be 30% w/w and 20% w/w, respectively. With

the addition of anionic and cationic surfactants, the viscosity and the electrical conductivity of the polymer

solutions were increased while the surface tension and fiber diameters of the nanofibers were decreased (p

< 0.05). However, nonionic surfactants have shown no statistically significant effect (p > 0.05). As a result,

electrospun nanofibers were produced using PVA and water and the diameters and properties of

nanofibers can be modified by controlling the parameters examined in the study.
