I need to preserve/store PVA-KOH hydrogel for my different experiments. How can I store the hydrogel without changing its characteristics and properties?
Sir, A proposed solution for this would be making nanocellulose-PVA composite.
Please refer to the article published in February 2022 on the title of "Preparation of nanocellulose-polyvinyl alcohol composite hydrogels from Desmodium intortum (Mill.) Urb.: Chemical property characterization".
