Abstract

The influence of the spatial structure of reinforcing fillers, such as ZnO and BN filamentous crystals of zinc oxide, as well as their content in an epoxy-polyamide polymer matrix on adhesion, physical and mechanical properties, water absorption and erosion resistance, was studied. It is shown that coatings containing ZnO filamentous crystals in their composition, which are clear spatial tetrahedra of four single crystals emerging from a single center, have a higher elastic coating under tension, as well as resistance to erosion compared to similar coatings containing BN filamentous crystals with a needle-like structure.
