Mahapatra, Swetapadma (2014) Fabrication and Characterization of PVDF - PZT (Navy type-VI) composites. BTech thesis.
Our work comprises preparation of homogeneous ceramics-polymer composites consisting of PZT (Navy Type VI) particles in the form of fillers and PVDF polymer as matrix, using a solution casting process. The structural, microstructural and dielectric properties of the composites film were investigated by X-ray Diffraction, Field Emmision Scanning Electron Microscopy, LCR Meter, respectively and discussed. The X-ray diffraction patterns indicate that with the addition of PZT, the polymer peak gradually flattens. PVDF matrix of the PVDF-PZT composite is contains mixture of á and â phase. The FESEM images show a uniform distribution of ceramic fillers in the polymer matrix. The composites prepared show greater dielectric permittivity and a reduced loss tangent. The results suggest that the introduced ceramic PZT fillers have a good influence on the polymer matrix and contribute to the improvement of the dielectric behaviour of the composites.
