Abstract The Sb‐hybridization strategy enables the precise construction of p‐n heterojunctions, which significantly enhances electromagnetic wave (EMW) absorption performance by optimizing interface polarization. In this study, an innovative in situ ion‐exchange method is developed to implement Sb hybridization, establishing built‐in electric fields within CoS 2 /Sb S 3 @CNFs that amplify polarization relaxation loss. This structural design synergistically combines a carbon‐skeleton‐induced conductive network with magnetic loss mechanisms , ultimately yielding exceptional EMW absorber. optimized composite demonstrates remarkable attenuation capabilities, achieving minimum reflection (RL min ) −57.53 dB at mm and effective bandwidth (EAB max 7.28 GHz (covering X‐band (8–12 GHz) Ku‐band (12–18 GHz)). study not only provides novel for designing advanced absorbers but also highlights significance heterojunction engineering functional composites.

This study evaluates the thermal conductivity of hemp-based insulation materials, focusing on loose bulk mixtures hemp fibre and hurd. Transient Plane Source (TPS) measurements were employed to assess these with a controlled variation in fibre-to-hurd ratio density. Samples from various suppliers, including those different diameters hurd contents, tested. The results indicate conductivities ranging 0.055 0.065 W/mK, demonstrating good performance. also highlights influence sample compression conductivity, higher leading both increased density conductivity. When compared conventional materials glass wool polystyrene, exhibited approximately double However, same resistance (R-value) could be achieved by increasing thickness insulation.
