摘 要: 利用已成熟的造孔工艺,制备得到了具有一定孔径(1.46 μm)和孔隙率(22.63%)的多孔聚酰亚胺材料(PPI).
选择3种不同极性与黏度的基础油,通过探究基础油极性和PPI含油特性与外界刺激响应行为,揭示了基础油的分
子结构和PPI含油特性与刺激响应行为的内在关联. 同时,以含不同基础油的PPI为摩擦材料样品,通过改变载荷和
速度的方式,实现多孔含油PPI的刺激响应,进而起到润滑的效果. 通过探究不同结构基础油的响应润滑行为,分析
磨损之后的形貌和组成结构,阐明了不同极性基础油的润滑机制,预期试验结果对多孔含油自润滑材料的设计提
供重要参考.

Abstract: Oil-containing porous polyimide (OPPI) with excellent mechanical strength and high-temperature resistance,is
normally used as a bearing retainer in certain conditions. The main mechanism of lubrication is primarily based on its
internal porous structure, which can provide durable lubrication through the release and re-absorption of stored
