Shear adhesive strength between epoxy resin and copper surfaces: a density functional theory study
Yosuke Sumiya, Yuta Tsuji, Kazunari Yoshizawa
Abstract
O surface is especially strong, and this change is large. This periodicity is similar to the stick-slip phenomenon in tribology. To further understand the shear adhesive forces, force decomposition analysis was performed, revealing that the periodicity of the adhesive stress originates from the DFT contribution rather than the dispersion one. The procedure proposed in this study for estimating shear adhesive strength is expected to be useful in the evaluation and prediction of adhesive and adherend properties.
