Electrical conductivity electromagnetic interference shielding(EMI) function materials have many potential applications. In order to analyze the EMI performance of graphite by size, composites were made by mixing with paraffin wax according to the size and content of graphite(KS6-150). In addition, we tried to check the existence of hybrid property by mixing graphite of different size. The composite was made into a donut-shaped specimen having an inner diameter of 3 mm and an outer diameter of 7 mm. The specimens were analyzed on a network analyzer using the GPC-7 kit in the frequency range of 2 GHz-18G Hz. KS6, the smallest size, showed the lowest emi properties. However, KS44 exhibited the best emi property even though it was not the largest size graphite, and KS75 and KS150 showed intermediate results between KS6 and KS44, even though they were larger than KS44. |
