Enhanced adhesion friction behaviors of nature rubber composites by applications of carbon nanotube: Experiment and molecular insight

The tribological performance of the rubber composite and tire products is affected by adhesion behaviors. The sliding friction tests of the CNT/NR composites and related simulations were performed to reveal the influenced factors of the adhesion behavior. The results indicated that the sliding friction process of the CNT/NR composite can be divided into three stages. The COF of the composite was significantly affected by the real contact area which was mainly determined by the CNT-influenced tensile properties, interfacial properties, and the load condition. This work expands the multiscale understanding of adhesion behavior and its influenced mechanism.
