“…In view of the lower processing temperature, as well as the flexible shape manufacturing of polymeric materials, polymeric materials had numerous advantages of production, such as lower energy consumption and costs than metallic materials, which has been widely favored in the industrial field [7,8]. Some polymeric materials demonstrate low friction noise, self-lubrication, and transfer filmforming mechanisms, which are considerable prospects to be adopted in the tribological industrial field, such as to gears, bearings, and seals [9,10]. However, the neat polymeric matrix generally presents inferior mechanical properties and load-bearing properties.…”
