| description | 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. |
