Abstract
Analysis on electromagnetic (EM) response properties of Modified Bisphenol A Epoxy Resin loaded with various types of commercial fillers, Multi-Wall CNTs (MWNTs), Single-Wall CNTs (SWNT), Carbon Black was made. The EM attenuation and reflection in Ka-band (26–37 GHz) provided by resin/SWCNT were measured as a function of the functional filler content (up to 1.5wt.%) and the EM coating thickness. A high THz attenuation ability is demonstrated in the range 0.2–3 THz by the CNT-based samples The transmission at 1 THz through the sample containing 0.5 wt.% of SWNT inclusions is 12 times less than through pure resin, and 3 times less in the case of MWNT incorporation. In the far-infrared frequency range (3–18 THz) a small reflection of the THz signal was observed (up to 5%) for all types of nanocarbon inclusions. The maximal reflection is demonstrated by the net epoxy resin, which denotes a strong screening effect of the given matrix. [1, 2].
