Abstract

The increased usage of electronic systems creates electromagnetic interference (EMI). Many research studies are explored different types of materials for electromagnetic wave shielding. However, very limited work is carried out on electromagnetic wave shielding materials for flexible cables used in electronic equipment. In the current work, three types of flexible tapes, namely L-Al-L, L-Ni-L, and L-Ni-L-Al-L, were developed using foils of aluminum (Al) and Nickel (Ni) laminated with Linear low-density polyethylene (LLDPE) (L). The developed tapes were characterized for electromagnetic shielding. L-Al-L and L-Ni-L tape's average total shielding effectiveness was 34.8 dB with 59 % absorption and 37 dB with 65 % absorption, respectively. At the same time, the hybrid tape showed enhanced shielding effectiveness of 45 dB. However, compared to the other two tapes, the L-Al-L tape appeared to be a better material because it was low in cost, thin, more flexible, and easy to wrap around the cable during processing.
