Background
The ultra-high molecular weight polyethylene has the same molecular structure as common polyethylene, but has extremely high molecular weight molecular chains and long molecular chains, and the interaction force between the molecular chains is mainly weak due to Van der Waals force. The long molecular chain prevents the crystallization, so that a large amorphous area in the long-chain polymer has low shear modulus and shear strength, and is easy to deform under the action of external force to form a smooth surface, so that the long-chain polymer has extremely low friction coefficient, the static friction coefficient is far smaller than or equal to the dynamic friction coefficient, and the self-lubricating property is good, and meanwhile, the high molecular material has low hardness, compared with a metal material, the strength and the modulus are reduced by 1-2 orders of magnitude, so that the real contact area when the high molecular material is in contact with the metal is large, the load is dispersed, and the contact temperature is reduced. But the surface energy of the macromolecular material is very small due to the inherent composition and structural characteristics of the macromolecular material, the surface adhesion property of the macromolecular material is poor, the surface adsorption of the macromolecular chain is difficult to generate due to the filler particles, the macromolecular chain has low hardness, the intermolecular acting force is small, the slippage or the fracture abrasion of the macromolecular chain is large under the action of external force, the surface hardness is poor, the abrasion resistance of abrasion resistant particles and the fatigue and abrasion resistance are poor, and the creep resistance is poor. The hardness and the wear resistance of the UHmWP E are still to be improved, so that the UHmWP E needs to be modified to obtain a wear-resistant material with more excellent performance.
