Synthesis of free-standing flexible Co-ZnO/PVDF composite films is realized by sol-gel technique. Modulation of the optical and microstructural properties of the above composite films with Co-doped nanocrystalline ZnO loading in PVDF matrix was studied critically. Uniform dispersion of Co-doped ZnO in PVDF matrix was indicated by SIMS studies. Information on the bonding environment was obtained from X-ray photoelectron spectroscopy and Raman spectroscopy studies. A very strong peak at ~695 eV for core level spectra of F1s along with those for C1s, Zn2p and Co2p dominated the XPS spectra of the composite films. Presence of the predominant β-phase of PVDF along with peaks related to ZnO nanocrystals in the poled sample was observed in the Raman spectra. [ABSTRACT FROM AUTHOR] |
