Summary: Carbon nanotubes have great potential for use in microelectronic packaging due to their excellent thermal conductivities. However, their high electroconductibility and poor radial conductivity limit their application in insulating materials. In this study, a heterostructured brushlike hybrid was prepared by anchoring amine-functionalized multiwalled carbon nanotubes onto insulating montmorillonite. The resulting composites exhibited improved thermal conductivity, mechanical properties, and thermal stability, providing a promising strategy for fabricating polymer composites.

Summary: This article introduces a novel lightweight foam material (CGF) composed of carbon nanotubes (CNTs) and reduced graphene oxide (rGO) for electromagnetic interference (EMI) shielding. The addition of 20 wt% CNTs expands the conductive network and increases the conductivity of the CGF material by 274.4%. The CGF material exhibits excellent EMI shielding effectiveness (SE) of 71.4 dB at a low mass per unit area of 12.5 mg·cm(-2). The CGF material also shows high comprehensive performance in terms of SE divided by density (SED) and mass per unit area (SEMA) values.

Summary: This study proposes an interesting strategy to simultaneously increase the tensile strength and fracture toughness of epoxy matrix by in-situ constructing block copolymer nanostructures. Through the optimization of nanostructures, the tensile strength and fracture toughness of epoxy matrix are increased by 19% and 236%, respectively, without lowering its Tg. The impact of block copolymers on the morphologies and transformation of nanostructures, the relationship between nanostructures and epoxy properties, and the strengthening and toughening mechanism are systematically studied. Moreover, the epoxy resins with excellent tensile properties and toughness are used to enhance the compressive and interfacial properties of CFRP composites.

Summary: A porous boron nitride (p-BN) filler network was fabricated to overcome the limitations of existing phase-change material (PCM) composites. The novel p-BN network was prepared by freeze-casting and BN synthesis by calcination. Thermally conductive sodium acetate trihydrate (SAT) composites were fabricated by dip casting and hot-pressing using a hybrid filler system of p-BN and raw BN. The prepared SAT/p-BN/BN composite exhibited a latent heat of 112 J/g, high thermal conductivity of 4 W/mK, and 548% higher tensile stress. The SAT/p-BN/BN composites can be used to realize efficient thermal management by combining the heat saving and heat dissipation enabled by large latent heat and high thermal conductivity, promoting the development of battery thermal management systems.

Summary: This study investigates the applicability of post-weld treatment techniques for large offshore structures, using empirical and theoretical analysis. The results show that ultrasonic impact treatment and pneumatic impact treatment can improve fatigue life but did not reach the expected level. These findings provide evidence for implementing post-weld treatment in offshore construction, but also raise the discussion of redesigning structures for cost-efficient automation.

Summary: This paper investigates the effect of impact damage on the fatigue behavior of CF/PEEK-titanium hybrid laminates. A fatigue life model is proposed to predict the S-N curves of the laminates based on energy dissipation approach. The energy dissipation behavior of the laminates under different experimental conditions is analyzed through post-impact fatigue tests, and the correlation between impact damage and fatigue dissipation energy is determined. The validity of the proposed model is verified through fatigue tests under different stress ratios and impact energy levels.
