In this study, we prepared 27 types of FBNs by using different ball milling parameters in the presence of amine molecules. Ball mill conditions, such as the ratios of hBN and the amine, rotation speeds, and treatment times of ball milling, were investigated, and then, the FBNs were covalently bonded with polyimide (PI) in all specimens.

In the first survey the ball mill was underperforming due to the low density in the mill, which was rectified in the second survey. The ball mill was grinding to a P 80 of 50 to 70 µm, therefore the traditional marker size (75 µm) was not applicable, and this can be seen by the increase in SSE for coarser sizes as the marker size approached P ...
