Polyimide(PI)engineering plastics are renowned for their excellent resistance to extreme temperatures,outstanding wear resistance,and self-lubricating properties,making them widely applicable in high-tech fields,such as aerospace,microelectronics,and mechanical manufacturing.In response to the growing and urgent demand for engineering plastics that maintain superior comprehensive performance in high-temperature environments,as well as the challenges posed by the trade-off between the high thermal resistance and processability of polyimide,and the scientific issue of simultaneously achieving high-temperature resistance,wear resistance,and self-lubrication,researchers have explored various modification strategies to enhance the tribological performance of polyimide under high-temperature conditions.This paper reviews the preparation techniques for high-temperature-resistant and wearresistant polyimide materials and systematically analyzes the influence of molecular structure design and filler selection on the high-temperature tribological properties of polyimides.Additionally,the challenges currently faced by high-temperature wear-resistant polyimide materials are discussed,and insights into future research directions are provided to promote the further development and application of polyimides in high-temperature wear-resistant fields.
