A process for the preparation of luminescent coating based on nanosized zinc oxide and polyvinyl pyrrolidone for the preparation of printed components of active and smart packs involves mixing of components, such as ethanol solution of ZnO nanoparticles with average size of 4.5 nm and concentration of 2⋅10M, aerosil (SiO), polyvinyl pyrrolidone with molar weight of 360,000 g/mol, polymethylmethacrylate and 1,2-dichloroethane. Components are mixed by addition of ZnO nanocrystals and polyvinyl pyrrolidone to ethanol solution, and prepared solutions are mixed up to full solubilization of components. The solubilization of polymethylmethacrylate in 1,2-dichloroethane and mixing of solutions prepared is carried out under thorough mixing and room temperature. Thereafter luminescent composition is applied on substrate. |
