Summary: In this study, the electromagnetic wave attenuation properties of polypyrrole-single-walled carbon nanotube nanocomposite hybrid films were investigated in the X-band region. The inclusion of single-walled carbon nanotubes in the polymer matrix improved the electromagnetic interference shielding performance. The AC conductivity and total shielding effectiveness increased with increasing single-walled carbon nanotube loading, reaching a maximum value. The results suggest that these nanocomposite films are suitable for lightweight, broadband electromagnetic interference shielding for radar and stealth applications.

Summary: This paper investigates the concept and possibility of synthesizing high entropy alloy (HEA)/carbon nanotube (CNT) nanocomposites. AlCoFeMnNi was chosen as the matrix with added 1 wt% CNT as reinforcement. The study shows that CNT addition significantly enhances the maximum shear strength of the alloy, and discusses the implications for mechanical properties and microstructure of HEA/CNT nanocomposites.

Summary: BaFe12O19-polypyrrolene nanocomposites were prepared via chemical oxidative polymerization of pyrrole monomers with the presence of BaFe12O19 powder. The composites exhibited a core-shell structure and showed no chemical interactions between BaFe12O19 and polypyrrolene. The nanocomposite was then used as a filler for UV-curable coatings, which demonstrated improved hardness, adhesion, and microwave absorption performance. The reflection loss was found to be below -10 dB within the range of 8.88-10.92 GHz when the absorbent sample proportion was 5-7%.

Summary: Bioelectronic devices are evolving from rigid to flexible materials, and thermally-drawn-fiber-based bioelectronics show promise due to their flexibility and integration of multi-functionalities. This study designed and fabricated microelectrode fibers made of carbon nanotube-based hybrid nanocomposites for electrochemical sensing. The fibers exhibited high sensitivity and long-term stability. In the future, multiple modalities can be integrated into a single fiber for various biological applications and health monitoring.
