The shearing behavior between ceramics and polymers is crucial for the performance of composite materials, especially in applications like total knee replacement, where it significantly impacts wear durability artificial joints. However, atomic evolution mechanism at interface during shear key influencing factors nanoscale are not fully understood. To address this, we use a molecular dynamics approach to model short PP chain additives SiO2/PP interface, focusing on underlying mechanisms under both smooth rough conditions. results show that with its roughness, induces significant deformation due hindering effect SiO2, whereas exhibits minimal deformation. As result, higher interfacial stress. study further examines impact finding increased roughness (larger amplitude or smaller wavelength) intensifies obstructive chain, leading larger Additionally, loading velocity considered. Within typical velocity, negligible, effects only occurring when exceeds several hundred meters per second. Finally, propose forming cross-linked network from short-chain can serve as an approximation long-chain discuss cross-linking. findings provide valuable insights into interfaces contribute understanding friction wear, particularly such replacement field biomedical applications.
