Summary: Flexible PEBA/CNT nanocomposites were fabricated for EMI shielding applications. CNTs nucleated the crystallization of the PA block of PEBA and induced the transformation of the crystals. Reducing the content of the PA block resulted in higher electrical conductivity and improved EMI shielding performances. When ionically conductive polyethylene oxide was used, the hindrance effect of PA crystallization on electrical percolation was effectively mitigated, allowing for high conductivity and enhanced amide dipole moment with a high PA content.

Summary: This study systematically investigates the correlations between the physical properties of six carbon nanotube (CNT) yarns produced by different spinning methods, and their structures and the properties of the constituent CNTs. The results show that the electrical conductivity of the yarns increases with the effective length of the constituent CNTs and the density of the yarns, while the tensile strength is more influenced by the packing density of the yarns, indicating the relative importance of interfacial interaction.

Summary: Embedding carbon fibers in CNT-PEEK powders can significantly improve the interfacial shear strength between the fiber and the matrix. The interfacial shear strength is negatively correlated with the fiber length, indicating brittle fracture at the fiber-matrix interface. The pulled out carbon fibers are still coated with the matrix, indicating strong adhesion at the interface.

Summary: A hybrid filler approach was chosen to address EMI pollution, with a focus on absorbance. Carbon nanofiller loading was limited to 0.6 vol.% to create a sustainable and affordable solution. Multiwall carbon nanotubes (MWCNT) and iron oxide (Fe3O4) nanoparticles were mixed in various ratios, achieving particle dispersion in a bio-based and biodegradable matrix. The nanocomposites showed promising results for EMI shielding, with high absorption at 30 GHz and reduced transmittance in the terahertz range.

Summary: The operative interphase properties around carbon nanotubes networks play a significant role in determining the strength of nanocomposites, with factors such as critical interfacial shear strength and interfacial shear strength defining the depth and power of the interphase area. Experimental results and parametric analyses are used to validate the established model, showing that both very low tau(c) and extremely high tau values can greatly increase the strength of nanocomposites. The strongest and densest interphase around CNT networks can significantly improve the strength of nanocomposites, while poor or thin interphase only has a minor effect on strength. Additionally, the size and density of CNTs also play a role in determining the strength of the nanocomposites.
