Abstract

Dielectric properties, thermal stability and sub-molecular structure of metal-polymer composites on the basis of polyvinylidene fluoride (PVDF) modified by sub-micro sized nickel powder were studied in this work by different methods such as dielectric spectroscopy, resistivity measurement, breakdown strength measurement, differential scanning calorimetry and optical microscopy. It was found that modification of PVDF by nickel particles results in the increase of both the volume resistivity by a factor of 1.24...15 and the melting and decomposition temperature by 5 °C and 48 °C for composite with an optimal nickel content compared with non-modified PVDF.
