Abstract:
The polymer was dissolved in twice distilled water, then nanoparticles were added to
it. The flow time of the solutions was measured, then the viscosity was calculated and the
surface tension of the solutions was measured by measuring the weight of the liquid drop.
Solutions were left at room temperature to form thin films that were subjected to variable
tension until they were cut and depending on the stress and strain of the samples. From the
results, an increase in the stress borne by the samples was noted with an increase in the
concentration of zinc oxide nanoparticles, and express the departure from the ideal elastic
behavior has values ranging from 3.71 to 54, but quantity pertaining to the ideal elastic
behavior has values ranging from 1.2 to 1.0. Increase viscosity of the solutions and their
surface tension. This makes it clear that it is possible to change some properties of the
PVA by adding zinc oxide nanoparticles, the sum of Huggins and Kraemer constants
values indicates that the samples were dissolved in a good solvent, as they can be used in
many areas of life such as industrial, medical applications.
