摘要: 聚四氟乙烯(PTFE)因具备优异的热稳定性、电绝缘性及低摩擦特性被广泛应用。然而，其显著的蠕变行为极大地限制了自身的应用范围。无机填料可有效改善聚四氟乙烯基材料的抗蠕变性能，且填料与聚四氟乙烯基体间的相互作用力对改性效果起着关键作用。本研究采用二维单层氧化石墨烯(GO)作为增强填料，制备得到氧化石墨烯-聚四氟乙烯(GO-PTFE)复合材料，实现了材料抗蠕变性能的显著提升。氧化石墨烯表面富含含氧官能团，可与聚四氟乙烯基体中的氟原子形成强界面氢键作用。理论计算与分子动力学模拟结果表明，GO-PTFE复合材料中存在强烈的分子间相互作用，该作用能够有效限制聚四氟乙烯分子链的运动，减缓其在外力作用下的滑移与变形，进而降低材料的蠕变程度。

Abstract: Polytetrafluoroethylene (PTFE) is widely used due to its excellent thermal stability, electrical insulation, and low friction characteristics. However, its significant creep behavior greatly limits its application range. Inorganic fillers can effectively improve the creep resistance of PTFE-based materials, and the interaction between the filler and the PTFE matrix plays a key role in the modification effect. This study employs two-dimensional monolayer graphene oxide (GO) as a reinforcing filler to prepare graphene oxide-polytetrafluoroethylene (GO-PTFE) composites, achieving a significant enhancement in creep resistance. The surface of graphene oxide is rich in oxygen-containing functional groups, which can form strong interfacial hydrogen bonds with fluorine atoms in the PTFE matrix. Theoretical calculations and molecular dynamics simulations indicate that there is a strong intermolecular interaction in GO-PTFE composites. This interaction effectively restricts the movement of PTFE molecular chains, reduces their slippage and deformation under external forces, and thereby decreases the material's creep extent.
