Preparation and transmission loss of the nano-crystal and polymer composite Bi4Ti3O12/PEK-c films
Bismuth titanate, Bi4Ti3O12 (BTO), is a typical ferroelectric material with useful properties for optical memory, piezoelectric and electro-optic devices. Its nano-crystals were compounded by the chemical solution decomposition (CSD) technique. The structure and size of BTO were analyzed by X-ray diffraction (XRD) and transmissive electron microscopy (TEM). Three sorts of composite films BTO/PEK-c with different BTO concentration were prepared by spin-coating method at certain conditions. In this article, the scattering losses in thin films were obtained using the photographic technique. The losses in the films with different BTO weight ratios were compared and analyzed.
