Compared to the conventional oil-containing material, the hierarchically porous oil-containing material exhibited high oil-content, and retained excellent mechanical properties and high oil-retention because of the synergistic effects of large pores and small pores. Furthermore, the lubricant stored in the hierarchically porous polyimide could release to the interface under thermal-and-mechano-stimuli, and the released lubricant could be reabsorbed into the hierarchically porous polyimide via the capillary-force offered by the porous channel. Based on the high oil-content and recyclable oil release/reabsorption, the hierarchically porous oil-containing polyimide exhibited excellent lubrication performance (coefficient of friction was 0.057). 2023-04-14T08:59:40Z 2023-04-14T08:59:40Z 2022 Book https://link.springer.com/article/10.1007/s40544-022-0642-5 https://dlib.phenikaa-uni.edu.vn/handle/PNK/7960 en application/pdf Springer
