Summary: In this study, the mechanical, DC conductivity, and electromagnetic interference (EMI) shielding properties of multiwalled carbon nanotubes (MWCNTs) and carbon fiber reinforced polypropylene (CNC) nanocomposites were investigated. The results showed that the combination of CF and MWCNT improved the tensile strength and modulus of the nanocomposites, and the percolation behavior improved the DC electrical conductivity. The CNC nanocomposites exhibited high EMI shielding effectiveness in the X-band for a 2 mm thick sample, and efforts have been made to develop a compatible EMI shielding material using multiple fillers.

Summary: Polyester nanocomposites reinforced with graphene nanoplatelets were prepared by high shear mixing and compression molding, with two different lateral sizes of GnPs. The electrical conductivity and electromagnetic interference (EMI) shielding behavior of these nanocomposites were experimentally investigated, showing that the alignment of GnPs and their lateral dimensions greatly influence the performance of the composites. The non-aligned smaller-size GnPs exhibited higher absorption coefficient and superior EMI shielding effectiveness compared to existing polymer composites with similar thickness.

Summary: This study presents a comprehensive numerical investigation on the electromagnetic interference (EMI) shielding capabilities of a conductive polymer nanocomposite incorporated with carbon nanotubes (CPNC) in the X-band. The results show that the EMI shielding effectiveness (SE) of CPNC can be improved by adjusting the weight percent (wt%) of carbon nanotubes (CNTs), the thickness, and the shape of the shielding material. The study highlights the exceptional absorption capabilities and lightweight nature of CPNC, making it a promising shielding material for aerospace and satellite communication applications.

Summary: A superhydrophobic conductive coating with micro-rough surfaces was prepared by adding polytetrafluoroethylene and multiwalled carbon nanotubes fillers to waterborne polyurethane. The addition of polytetrafluoroethylene reduced the friction coefficient and improved the wear resistance of the coating, but decreased its adhesion and corrosion resistance. The best structure and combination property of the coating were achieved with a mass ratio of 7:3:0.2 for waterborne polyurethane, polytetrafluoroethylene, and multiwalled carbon nanotubes.
