Summary: Fiber-reinforced polymer composites, especially carbon fiber-reinforced epoxy (CFRE) laminates, have been widely used in the aircraft and aerospace industry. The interface between the matrix and fiber plays a critical role in determining the overall structural properties of CFRE laminates. In this study, electrophoretic deposition (EPD) was used to deposit covalently coupled multiscale graphene oxide (GO)/carbon nanotube (CNT) nanoconstructs onto carbon fiber (CF) fabric, resulting in improved flexural strength and interlaminar shear strength compared to the neat CFRE. The deposition of GO/CNT nanoconstructs improved the performance of CFREs by enhancing wettability, surface free energy, and surface roughness.

Summary: Hybrid graphene oxide-polyethyleneimine-coated carbon fibers (ACF/GO-PEI) were prepared through electrophoretic deposition (EPD) to enhance the interfacial performances between carbon fibers and epoxy matrix. The combination of rigid GO sheets and flexible PEI polymer improved the mechanical performances by providing mechanical interlocking and bridging effects. The uniform distribution of GO-PEI sheets on carbon fiber surface increased the surface roughness and energy, leading to a significant enhancement of the interfacial shear strength (IFSS) of the ACF/GO-PEI reinforced epoxy composite.

Summary: In this study, the modulus difference between carbon fiber (CF) and resin was reduced and a gentle modulus transition was achieved through the structural design of CF and resin, which resulted in enhanced interfacial properties of the CF/EP composite.

Summary: This study presents a nature-inspired interface strategy to fabricate high-performance and low-cost fiber-reinforced composites. By coating a heterostructural montmorillonite-multiwalled carbon nanotube (Mt-MWCNT) hybrid on the surface of glass fibers, a nacre-like interface layer is formed, improving the strength and toughness of the glass fiber/ epoxy composites. The enhanced dispersion and strong bonding of the Mt-MWCNT hybrids contribute to the improvement in interlaminar shear strength, work of break, storage modulus, and thermal stability of the resulting composites.

Summary: Noise pollution poses a threat to health and well-being, and its prevalence has been increasing. Incorporating fluorescent single-walled carbon nanotubes (SWCNTs) into epoxy resins can improve their sound-dampening capabilities. The DNA-SWCNT/epoxy composites showed the highest transmission loss, with an 18% improvement compared to epoxy alone, and the optimal concentration of DNA-SWCNT was found to be 2 mg L-1. Additionally, the near-infrared fluorescence of SWCNTs was utilized to characterize their distribution within the epoxy resin.

Summary: Polypropylene and polylactide-based composite fibers filled with carbon nanofibers were produced using a melt technology. The carbon nanofibers exhibited even distribution in the polymer matrix and orientation along the fiber extrusion direction. The dependence of electrical resistance on filler concentration in the composites showed percolation behavior, described by a double Boltzmann function. The study identified four sections in the resistance-concentration dependence and analyzed the reasons for the formation of electrically conductive circuits.

Summary: This study coated carbon fibers (CFs) with nanosized-polycaprolactone (PCL) particles to create a functionalized self-healable interphase that can fully recover the interface shear strength between CFs and a debonded epoxy matrix. PCL nanoparticles were deposited on CFs through electrophoretic deposition, resulting in different coating morphologies based on applied voltage levels. After microdebonding tests, an electric current was applied on CFs to activate thermal healing using the Joule effect. The PCL nanocoating showed outstanding repairing efficiency by completely restoring the original interfacial shear strength.

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.
