Preparation of an ultra-low profile and high peel strength copper foil …
The obtained results indicate that the surface of the copper foil exhibits an average diameter of 420 nm copper nanoparticles and a 52% higher surface area than bare copper foil, contributing to the improved peel strength from 0.05 to 0.5 N mm −1. Further contact angle research shows that the rice-grain copper nanoparticles reduced the ...

Aluminium - Attributes and Properties of Aluminium Foil - AZoM.com
2002年5月28日 · Foil is a very thin sheet of rolled aluminium supplied in its pure form (‘commercial purity’) or in a variety of alloys and tempers which give a wide choice of tensile properties. The thickness of foil ranges from the thinnest currently produced commercially at about 0.0065 mm (or 6.5 µm) to the defined upper limit of 0.2 mm (or 200 µm).
High-purity aluminum foils containing a small amount of several elements focused on the transition metals of Fe, Mn, Co and Cu, were used in this study. The surface segregation phenomena were studied by Rutherford back scattering spectroscopy (RBS) and transmission electron microscopy (TEM) on the foils, after various heat treatments. 2.
Wear resistance mechanism of graphene/copper composite foils …
2024年1月1日 · In this study, we prepared pure copper foils and Gr/Cu composite foils with different microstructures by adjusting the parameters of P-EP. The Gr/Cu composite foils with a bimodal structure exhibited the best wear resistance.
utilizes surface acoustic wave assisted annealing to flatten metal foils by eliminating the surface steps, eventually transforming commercial rough metal foils into ultraflat substrates.
Here, we propose a Cu foil kinetic model with abundant nanocavities possessing higher reaction rate constant k to steer the ratio of C2H4 to the competing CH4 during CO2 electroreduction.
Folding and Fracture of Single-Crystal Graphene Grown on a Cu(111) Foil
A single-crystal graphene film grown on a Cu(111) foil by chemical vapor deposition (CVD) has ribbon-like fold structures. These graphene folds are highly oriented and essentially parallel to each other. Cu surface steps underneath the graphene are along the <110> and <211> directions, leading to the formation of the arrays of folds.
High Tensile Properties and Low Surface Roughness of Gr/Cu Foils …
Cu foil with low surface roughness and high tensile properties is a challenge in the field of electronic materials. In this research, the graphene/copper foils (GrCFs) have been fabricated by direct current electrodeposition. The changes in the structure and properties of GrCFs caused by mechanical agitating rate were investigated.
