Comparison between Viscosity and Surface Tension of Polyvinylpyrrolidone/ Silver Nanoparticle (PVP/ AgNP) Solutions and Polyethylene Glycol/ Silver Nanoparticle (PEG/ AgNP) Solutions
Abstract
In the present study, viscosity and surface tension of Polyvinylpyrrolidone
(PVP) solutions and Polyethylene glycol (PEG) solutions in water and nitric acid with
different concentrations (0.0, 0.2, 0.4, 0.6, 0.8 and 1.0 %) of silver nanoparticles have been
measured. However, the relative viscosity of PVP/ AgNP solutions increased from 2.245 to
2.585 and the relative viscosity of PEG / AgNP solutions increased from 1.150 to 1.204.
Viscosity is a significant parameter during the electrospinning process. While the surface
tension of the PVP/ AgNP solutions has changed from 0.052 Nm-1 to 1.46 Nm-1, it has
changed from 0.063 Nm-1 to 0.160 Nm-1 for PEG / AgNP solutions. In this paper, attempts
were made to obtain improvements to the properties of samples by comparing them with
the pure samples of polymers. I think that there are personal errors in the measurements.
These results can be used in medical, industrial applications and in scientific studies.
