In-situ Growing Carbon Nanotubes on Nickel Modified Glass Fiber Reinforced Epoxy Composites for EMI Application

Yu Liu et al.

Summary: This study focuses on preparing epoxy composites with excellent electromagnetic interference (EMI) shielding performance by coating glass fiber (GF) with a thin layer of nickel followed by grafting carbon nanotubes (CNTs) array. The results show that incorporating nickel-coated GF with CVD grown CNTs can achieve the best EMI shielding effectiveness among the composites, with a lower CNT content compared to GF without nickel coating.

Design of a Lightweight Multilayered Composite for DC to 20 GHz Electromagnetic Shielding

Paul Clerico et al.

Summary: The research aimed to design a trilayer composite for electromagnetic shielding, showing good shielding effectiveness over a wide frequency range from 1 Hz to 20 GHz. Analytical and numerical models were used to determine the shielding effectiveness, with the use of homogenization and AMSL methods to simplify numerical calculations. The proposed composite demonstrated high shielding capacity in both near-field and far-field, with shielding effectiveness exceeding 17 dB and 75 dB, respectively.

Lightweight high-performance carbon-polymer nanocomposites for electromagnetic interference shielding

Shan Liu et al.

Summary: This work discusses the state-of-the-art methods for fabricating lightweight electromagnetic interference shielding materials based on porous carbon/polymer nanocomposites. The key challenge lies in creating effective conductive networks at low filler loadings. Design strategies include the use of carbon foams with polymer backfilling, the use of carbon-based hybrid fillers, and the formation of segregated structures in conductive polymer composite. The review also covers electrical conductivity and electromagnetic interference shielding performances, along with potential applications.
