Summary: The thermal conductivities of epoxy composites with Al-exfoliated graphite nanoplatelets increased with filler content, with partially inserted composites showing the highest thermal conductivity. Fully inserted composites had the highest tensile and flexural moduli, but all composites exhibited lower tensile and flexural strengths with increased filler content due to weaker interfaces between the epoxy matrix and filler.

Summary: The non-covalent modification of CNTs and xGnP with ILs had a significant impact on the PU matrix. The electrical conductivity and EMI SE of the composites were influenced by the loading, dispersion of the fillers, and the nature of IL. Composites with IL105 showed higher electrical conductivity and EMI SE due to better interaction with the PU matrix compared to composites with IL101.

Summary: The study showed that PA6 composites filled with graphene nanoplatelets exhibit slight improvement in thermal stability, but significant advantages in terms of tensile and flexural properties compared to the neat matrix. The filler content of graphene nanoplatelets has a notable impact on the strength parameter. However, when the content of GNPs exceeds 3%, the predictable worsening of graphene sheet dispersion affects the ultimate performance of the more concentrated formulation.

Summary: This research focuses on the microstructural evolution and mechanical behavior of Cu composites incorporated with graphite nanoplatelet (xGnP, where x = multiple layers of graphene) reinforcement. The dispersion of nanoplatelets in the Cu matrix is achieved through ultrasonication. The fabrication is carried out through powder metallurgy followed by furnace sintering and spark plasma sintering. Results show a homogeneous distribution of graphite nanoplatelet in the Cu matrix at lower loading levels, leading to enhanced mechanical properties and wear behavior. However, at higher loading concentrations, there is a non-uniform distribution, formation of bigger conglomerates, and generation of pores, which limits the mechanical performance.

Summary: This study presents an innovative approach to improve the photovoltaic conversion characteristics and stability of perovskite solar cells through carbon electrode interface modification. By in-situ polymerization and carbonization on the surface of nano-graphite, a dendritic structure carbon electrode is formed, reducing the work function and aligning the energy levels with perovskite. This leads to improved charge and hole collection efficiency, resulting in increased photovoltaic conversion efficiency. Furthermore, the modified carbon electrode-based perovskite solar cells exhibit exceptional stability, maintaining high efficiency even without encapsulation.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.

Summary: A detailed understanding of the interaction between molecules and two-dimensional materials is crucial for incorporating functional molecular films into next-generation 2D material-organic hybrid devices. This study compares the energy level alignment of different-sized fullerenes on a Moire superstructure and finds that C-84 fullerenes can be either neutral or negatively charged depending on slight variations of the electrostatic potential. This discovery suggests a new path to achieve ambipolar charge transfer without overcoming the electronic gap of fullerenes.
