Special Issue Information

Dear Colleagues,

The study of surfaces and interfaces is critical for determining the electrochemical reaction of nanomaterials and modifying their properties, for which there are many strategies. The modification and cladding of the surface and interface can be employed to prevent unwanted agglomeration of nanomaterials, exploit their size and interfacial effects, and impart special functions and properties on them. The doping effect is another construction strategy used to optimise the properties of the surface and interface by changing the charge density distribution of the material through the doping of metals and non-metals. In addition, the construction of heterogeneous structures can improve and optimise the material properties through the effective compounding of different components and their synergistic effect. Additionally, surface and interface regulation strategies, such as size effect and geometry electronic structure regulation, morphology and crystal surface regulation, surface interface defect regulation, and interphase interaction regulation, are critical. The study of the surface and interface modulation of nanomaterials aims to develop ways to effectively optimise the properties of nanomaterials and influence the thermodynamic processes and stability of these materials, thus having a decisive impact on the microenvironment of nanomaterial applications. Therefore, this field has become an important research area in nanoscience.

This Special Issue will introduce surface and interface science applications in the field of nanomaterials, with a special focus on, but not limited to, the study of material surfaces and interfaces to optimise energy device performance, prevent corrosion, and protect materials.

The homogeneous distribution of carbon nanotubes (CNTs) in the Cu matrix and good interfacial bonding are the key factors to obtain excellent properties of carbon nanotube-reinforced Cu-based composites (CNT/Cu). In this work, silver-modified carbon nanotubes (Ag-CNTs) were prepared by a simple, efficient and reducer-free method (ultrasonic chemical synthesis), and Ag-CNTs-reinforced copper matrix composites (Ag-CNTs/Cu) were fabricated by powder metallurgy. The dispersion and interfacial bonding of CNTs were effectively improved by Ag modification. Compared to CNTs/Cu counterparts, the properties of Ag-CNTs/Cu samples were significantly improved, with the electrical conductivity of 94.9% IACS (International Annealed Copper Standard), thermal conductivity of 416 W/m·k and tensile strength (315 MPa). The strengthening mechanisms are also discussed. Full article
