“…[25][26][27] However, when the polymer bearings suffer extreme conditions including low-speed and high-load conditions, it is more difficult to form a water film. [28] HDPE modified by GNP is an ideal way for two-dimensional materials practical applications in polymer bearings. [29,30] Many scholars have agreed with and proved that there was a graphene-lubricated layer formed during friction to improve the lubricating conditions.…”

Controlling unabridged graphene-lubricated layers and extending their last times can extend the service life of polymer moving components. The friction reduction behaviors of graphene nanoplatelets (GNP) on the tribology performances of high-density polyethylene (HDPE) were studied based on friction experiments. The mechanical properties, coefficient of friction (COF), surface topography, tribo-layers wear synthetically charactered to analyses the friction reducing processes. The results showed that the GNP presented a limited friction reduction to HDPE, and it could be controlled by the mass contents of GNP, load and speed. The proper content of graphene maintained the effective GNP tribo-layers for a long time and led to a long duration of friction reduction. Decreasing load or speed weakened the wear processes, which was useful for maintaining the effective GNP tribo-layers for a long time, and reduced the COF. The knowledge will provide experimental support for improving the selflubricating performance and abrasiveness of polymers.

“…The collision and bouncing of bubbles with an air-liquid interface or liquid-solid interface are common phenomena in a wide range of industrial applications, such as mass transfer in bubble column reactors [1][2][3], crude oil processing [4][5][6], froth flotation in mineral processing [7][8][9][10] and wastewater treatment [11,12]. 4 When rising bubbles approach an air-liquid interface or liquid-solid interface, either foam or wetting film, i.e.…”
