Abstract

In this paper, we investigated how to improve the EM wave absorption properties with Al(OH)₃. Where we compared results for the case of the absorption properties of samples containing 0 wt%, 1 wt%, 3 wt%, 5 wt%, and 7 wt% of Al(OH)₃. The absorption property curve just has the tendency to improve the characteristics at 5 wt% of Al(OH)₃ at Sendust, and at 3 wt% of Al(OH)₃ at Carbon. As a result, the optimized composition ratio of Al(OH)3 is 5 wt% at Sendust and 3 wt% at Carbon. Al(OH)₃ is an important material to increase EM wave absorption in Sendust or Carbon EM wave absorbers.
