Synthesis and characterization of hybrid PVA/Al2O3 thin film

This paper presents the synthesis and characterization of hybrid PVA/Al2O3 thin film at room temperature (RT) and respectively under hydrothermal conditions (HC). The synthesis starts from commercially available Al2O3 and 10% PVA solution. When working at RT, regardless of the mixing ratio of PVA and Al2O3 (1:4; 1:1 and 4:1 wt) two phases can be identified by SEM due to the high difference between the densities of the two components. When working under HC, the hybrid PVA/Al2O3 thin film is homogeneous due to the reactions which occur between PVA and Al2O3 as proved by XRD and FTIR.
