| Abstract: | In this work, the effects of magnetic field induction on electrical and electromagnetic shielding properties of conductive silicon rubbers (CSRs) filled with Ni-coated carbon fibres (Ni/CFs) have been investigated. When the magnetic field intensity is above the threshold value of 0.10?T during the vulcanisation, it is beneficial to their electrical property that the volume resistivity decreases from 48.7?Ω·cm to 1.57?Ω·cm, owing to the orientation alignment of Ni/CFs in CSRs filled with Ni/CFs (40?phr). Moreover, with the aids of magnetic field induction, the prepared CSRs with lower amount of Ni-CF filler can receive better electromagnetic shielding of 65?dB in 500?MHz–3?GHz, which reduce cost effectively. This vulcanisation process shows promises for various applications in power transmission and transformation industries. |
