摘要：The hybrid of organic semiconductor copper phthalocyanine (CuPc) and inorganic semiconductor titanium dioxide (TiO2) was synthesized by a simple ball milling processing. Structural properties of CuPc-TiO2 composites were characterized by X-ray diffraction (XRD), and transmission electron microscopy (TEM). The CuPc-TiO2 hybrid was used as nanofiller within flexible dielectric poly(vinylidene fluoride) (PVDF) matrix. The dispersion of fillers was characterized by cross-section scanning electron microscope (SEM). The conjugated structure of CuPc nanosheets in CuPc-TiO2 hybrid could provide huge p-associated orbital for electron delocalization and thus enhanced the dielectric constant of the corresponding PVDF composites. The dielectric constant of PVDF composite filled with 20%(CuPc-TiO2) ball-milling hybrid was 114.71 at 1 Hz, which was almost 7.8 times higher than the dielectric constant of 20% TiO2-PVDF composite and 20 times higher than that of the pure PVDF.
