The thesis is devoted to the study of the properties of the composites with two-dimensional carbon particles. It was shown, that the redistribution effect appears in polymer composites with the two-dimensional carbon particles after heating above the glass transition temperature. During the first heating, the resin becomes less viscose, and the particles obtain enough mobility for the redistribution. It was also demonstrated, that the dielectric and piezoelectric properties of the composite material with ferroelectric particles may be significantly improved by means of graphitic nano platellettes (GNP) addition due to better distribution and creation of the local electric fields. The numerical model for the calculation of the electric percolation threshold of randomly distributed was developed. The model allows calculating the percolation for different dimensionality (0D, 1D, 2D) of the inclusions and for different combinations (hybrid case) of the different types of fillers. |
