Zusammenfassung:A composite of zinc stannate (ZnSnO 3 ) nanocubes and poly(methyl methacrylate) (PMMA) has been prepared and deposited on a flexible substrate polyethylene terephthalate (PET) through electrospray deposition (ESD). This fabrication technique has been found very effective for deposition of this composite as thin film. ZnSnO 3 is an inorganic biocompatible and piezoelectric material while PMMA is a transparent and durable organic polymer material. ZnSnO 3 naocubes have been synthesized via an aqueous solution method and ZnSnO 3 /PMMA composite has been deposited as thin film on PET through ESD. The average layer thickness of the as deposited ZnSnO 3 /PMMA composite film on PET was found to be 149 nm. Morphological and structural characterization of ZnSnO 3 nanocubes through FESEM and XRD showed its size uniformity and crystalline nature. The size of the ZnSnO 3 nanocubes was estimated by FESEM analysis which was around 50–70 nm. The chemical composition has been investigated with the help of FTIR and Raman spectroscopy. The optical characterization of as deposited ZnSnO 3 /PMMA composite film through UV/Vis spectroscopy showed an average transmittance of around 92 % and electrical characterization exhibited resistivity of approximately 50 × 10 5  Ω cm. This dielectric nature of ZnSnO 3 /PMMA composite film indicates that this composite material can be employed as dielectric layer in printed electronics.
