The discussion focuses on creating a ZnO solution for depositing a layer on glass substrates using the drop casting method. It highlights that ZnO powder typically results in a suspension unless an acid is used, which alters its chemical composition. The use of nano-particle ZnO is recommended for achieving a stable suspension, commonly utilized in applications like sunscreen and deodorants. Additionally, incorporating a thickening agent can extend the working time of the suspension.
