With growing demands arising from technology development for highly durable and easily moldable materials in flexible electronic devices, electromagnetic interference (EMI) materials are gradually shifting from rigid metals to soft polymer composites. Current flexible EMI shielded materials with high electrical conductivity have limited mechanical robustness owing to unstable filler–polymer structures and filler agglomerations. This work prepares highly conductive EMI shielding materials from steel fibers (SFs) and polypropylene (PP) composites using extrusion preprocessing and postprocessing methods, such as compression molding and injection molding. The extrusion process provides highly crystalline SSF/PP composites with mechanical strength at break of up to 30 MPa and a high elastic modulus of up to 2.5 GPa. Extrusion followed by injection processing forms an aligned structure of SSF and creates β crystalline phases inside the PP matrix. The SSF/PP composites prepared by the extrusion-injection process demonstrated flexibility and bending to 180° with full recoverability and strain to failure of 250% for 0.2–1 vol % and 80% for 2 vol % SSF. 2 vol % SSF/PP composites exhibit a high out-of-plane electrical conductivity of 0.25 S cm–1, an in-plane electrical conductivity of 12 S cm–1, an EMI shielding effectiveness of 25 dB, and a high impact strength of 4.7 kJ m–2. The study provides a facile, scalable, and solvent-free strategy for high-performance, soft, and durable EMI shielding materials with great potential for flexible and portable electronics.

“…Currently, there are three main methods to intensify the EMI shielding capability of carbon fiber reinforced polymer composites, namely adding conductive fillers to the matrix, [10][11][12][13][14] coating the fiber with a metallic layer, [15][16][17][18][19][20] and blending a metal wire mesh into the carbon fiber fabric. [21][22][23] To be specific, Zhang et al 11 proposed a method for the rapid preparation of long carbon fiber reinforced polyamide 6 (PA 6)/nickel powder composite material. This method involved incorporating nickel powder into the PA 6 matrix.…”

This article investigates the use of nickel electroplated carbon fiber (Ni‐CF) fabric to enhance the electromagnetic interference (EMI) shielding capability of carbon fiber reinforced thermoplastics (CFRTs), particularly for automotive and aerospace applications. The study examines the influence of nickel electroplating parameters of carbon fiber on the morphologies of carbon fiber fabrics. Ni‐CF reinforced polyamide 6 (Ni‐CF/PA 6) was prepared by the film‐stacking method. The flexural properties analysis demonstrates a 21.1% increase in flexural strength for Ni‐CF/PA 6 composites compared to as‐received carbon fiber reinforced PA 6 (CF/PA 6) composites. Additionally, the introduction of nickel layer significantly improves the EMI shielding efficiency of CF/PA 6 composites, with the average shielding efficiency increasing from 23.5 to 31.6 dB within the X‐band and Ku‐band frequency ranges. Scanning electron microscope (SEM) analysis confirms that the nickel layer enhances the interfacial bonding between the PA 6 matrix and the Ni‐CF, which is attributed to the micro cone‐shaped structures of the nickel layer. Overall, the electroplating method effectively modifies the carbon fiber surface, resulting in composite laminates with enhanced mechanical properties and superior EMI shielding efficiency. These findings provide valuable insights for the development of advanced carbon fiber reinforced composites with improved functionalities in various applications.Highlights The electroplating method is used to process the nickel electroplated carbon fiber fabrics. The introduction of micro cone‐shaped structure nickel on the fiber surface by electroplating provides the mechanical interlocking between carbon fiber and matrix. The nickel electroplated carbon fiber can significantly increase electromagnetic interference shielding capability of carbon fiber reinforced thermoplastic composites.

This work presents the comprehensive characterization of alkali treated areca fruit husk fiber (AAFHF) an industrial agro-waste reinforced unsaturated polyester resin (UPR) matrix hybrid composite with silicon carbide (SiC) nanoparticles as filler material. Hybrid composite plates were fabricated with 40 wt% of AAFHF and diverse wt% of SiC nanoparticles ranging from 1 to 4 wt% in steps of 1 wt%. The effect of wt% of SiC nanoparticles in hybrid composite over mechanical, morphological, wear, thermal and water absorption characteristics was investigated. The findings help to conclude that a hybrid composite plate with 3 wt% filler content excels in overall properties. Meanwhile, the accumulation and meager scattering of SiC nanoparticles in composite deteriorated the functional characteristics when the wt% of filler content enhanced to 4 wt%. Also, the failure pattern and interaction between AAFHF, SiC nanoparticle and UPR were understood from the images obtained using Scanning Electron Microscopy (SEM). In addition, the availability of functional groups, crystallite size and crystallinity index was obtained from Fourier transform infrared (FTIR) spectrum and X-ray diffraction (XRD) analysis for the optimum filler content respectively. Moreover, the achieved results suggest the suitability of the developed composite for marine and lightweight applications.
