Due to the plate-like structure, when the particle size of the non-conductive metal compound particles having the 10m or P6 3 / mmc space group structure is increased, the increase in the particle size may be more reflected due to the large aspect ratio.
- the dispersibility in the high-polymer resin of the non-conductive metal compound particles can be significantly lowered, and the brittleness can be greatly increased to further lower the mechanical properties such as the layer strength of the polymer resin.
