摘要: Abstract Strong adhesion between rubber and brass has been considered to arise mainly from the mechanical interaction, which is characterized by dendritic interlocking at interface. In order examine a possible contribution of chemical state analysis was carried out for model molecules natural (2-methyl-2-butene isoprene) adsorbed on Cu2S, key species adhesion, means photoelectron spectroscopy (PES). Absence C 1s PES component associated with C=C bonds appearance adsorption-induced components in S 2p region indicate that interact Cu2S surface via bond form C–S covalent bonds. This proves interaction certainly plays role rubber–brass along interaction.
