Influence of ZnO Nanofillers on the Permittivity of New Cold-Curing Class Polyurethanes

Popis výsledku v původním jazyce

An important group of polymers with a wide range of applications is polyurethanes (PUR). In this contribution two-component system (2K PUR) is used to describe the effect of filler ZnO (Zinc Oxide) on the dielectric properties of industrial polyurethane marked as VUKOL N22 (from VUKI a.s.). From the results of the investigations carried out, it is evident that the incorporation of ZnO a decrease of real permittivity was observed due to a lower mobility of polymer chains connected to nanoparticles. Lower dielectric losses are associated with the lower relative permittivity. The SEM pictures show the distribution nanoparticles in matrix. Temperature-related relaxation peaks were observed in dissipation factor frequency spectra. Scanning Electron Microscopy (SEM) was used to measure the size and distribution of dispersed particles, and Energy Dispersive X-ray (EDX) analysis was used to confirm the chemical nature of particles.
