Summary: This study investigates the impact of graphene flake size on the properties of PVDF-HFP composites, demonstrating that larger graphene flakes result in higher electrical and thermal conductivity, as well as tensile strength. The composite films with larger graphene flakes achieved ultra-high in-plane electrical conductivity, in-plane thermal conductivity, and tensile strength. These values are reported to be the highest among PVDF-based composites in the literature.

Summary: With the development of electronic products towards flexibility, miniaturization and high frequency, the demand for conductive polymer composites (CPCs) with ultra-low thickness, outstanding electromagnetic interference (EMI) shielding effectiveness (SE) and excellent mechanical properties is growing. In this study, a double-structured silver fractal dendrite/polyvinylidene fluoride (AgFD/PVDF) composite film was successfully fabricated. The film exhibited high electrical conductivity and remarkable EMI shielding performance, as well as good mechanical strength, indicating its great potential for practical applications in high-efficient EMI protection.

Summary: This study presents a method for fabricating poly(vinyl alcohol) (PVA) -copper oxide (CuO) nanocomposites using water as a solvent. The addition of copper chloride salt to the PVA solution and heating produces CuO nanoparticles. The agglomeration of nanoparticles enhances the fluorescence behavior of CuO nanoparticles. The mechanical and electrical properties of the nanocomposites vary with concentration and heating period.

Summary: Nanolaminate with alternating layers of nanocrystalline Cu and amorphous CuZrTi is proposed as a highly stretchable and conductive interconnect material in stretchable devices. The optimal thicknesses of the constituent layers are 50 nm for nanocrystalline Cu and 20 nm for amorphous CuZrTi, resulting in an elastic deformation limit of 3.33% and an electrical conductivity of 11.83 S/mu m. The nanolaminates exhibit enhanced elastic deformability and conductivity, enabling the maintenance of interconnect performance under cyclic stretching with tensile strains of 114% and 30% in different structures.

Summary: This article investigates the impact of multistage mechanical activation of multilayer carbon nanotubes (MCNTs) with graphite on the temperature field distribution uniformity and starting current reduction of nanomodified elastomers for self-regulating electric heaters. The results show that mechanical action and thermal effects play a role in the distribution of the temperature field, with a significant reduction in starting current and stabilization of temperature observed. The presence of self-regulation is evident in maintaining a certain level of temperature.
