Synthesis and characterization of ZnO growth on PMMA thin film by solution-immersion method as a potential in UV related application / Noor Aadila Abd Aziz

In this study, preparation and characterization of ZnO grown on PMMA thin film was investigated. The procedure was divided into two steps; preparation of PMMA thin film followed by growing ZnO on PMMA thin film. The PMMA thin films were prepared using sol-gel spin-coating method. The AFM image showed that the homogenous thin film is obtained at 6 x 103 wt% of PMMA. It was found that the PMMA thin film gave good UV absorption for 7 layers of deposition on the glass substrate at annealing temperature of 100° C. The ZnO were next grown on PMMA thin film using solution-immersion method with Zn(NO3)2.6H2O as a precursor and C6H12N4 as a stabilizer. The UV absorption of the film almost covers the UV range up to about 400 nm and the visible light transmission was permitted. Thus, the sample was able to prevent the penetration of UV light and maintained transparent which could be applied in transparent UV-protective coating and UV-shielding windows.
