“…In addition, the 'PI + AGNS' nanocomposite showed excellent wear resistance in seawater at CoF = 0.16 and WR = 1.68·10 -4 mm 3 /Nm (PI, B-o-D; Ra = n/d; DSF, SWL; V = 300 r/min; t = 30 min; P = 5 N; the counterpart is the GCr15 steel ball with a diameter of 4 mm). Zhou, S., et al investigated 'PI + FG' nanocomposite films (FG is fluorinated graphene in amounts of 0.5-2.0 wt.%) under different friction conditions [55]. CoF levels of the nanocomposites decreased slightly compared to that for neat PI.…”

High Performance Polymer Composites: A Role of Transfer Films in Ensuring Tribological Properties—A Review

2022

View full text Add to dashboard Cite

The purpose of this review is to summarize data on the structure, mechanical and tribological properties, and wear patterns of composites based on high-performance polymers (HPPs) intended for use in friction units. The review includes three key sections, divided according to the tribological contact schemes regardless of the polymer matrix. In the second part, the analysis of composites is carried out in point contacts. The third section is devoted to the results of studies of HPP-based composites in linear ones. The fourth section summarizes information on flat contacts. Particular attention is paid to the formation of transfer films (TFs) in the contacts and their influence on the tribological patterns of the studied rubbing materials. As a conclusion, it is noted that the challenge of experimental methods for analyzing TFs, stated by K. Friedrich, is effectively solved in recent studies by the XPS method, which enables us to accurately determine their composition. Although this determination is completed after the tribological tests, it allows not only a more accurate interpretation of their results considering specific conditions and loading schemes, but also the ability to design HPP-based composites that form required TFs performing their preset functions.

“…Polyimide composite has good self-lubricating properties and can be used in dry friction without lubrication. Recently, PI composite applications in tribology condition, when the content of FG is 0.5%, the specific wear rate of 0.5FG/PI decreased by 51.2% less than pure PI [48]. Different graphene derivatives showed to enhance the tribological properties as reinforced polyimide composites.…”

“…Unlike other research works which incorporated unmodified graphene, evenly dispersed sulfonated graphene in polyurethane [ 74 ] and chloroform-modified fluorinated graphene (FG) in PI [ 75 ] were documented. COF of the FG/PI nanocomposites were lower than that of pure PI, regardless of the friction conditions.…”

Effect of Nanofillers on Tribological Properties of Polymer Nanocomposites: A Review on Recent Development

et al. 2021

View full text Add to dashboard Cite

Polymer nanocomposites with enhanced performances are becoming a trend in the current research field, overcoming the limitations of bulk polymer and meeting the demands of market and society in tribological applications. Polytetrafluoroethylene, poly(ether ether ketone) and ultrahigh molecular weight polyethylene are the most popular polymers in recent research on tribology. Current work comprehensively reviews recent advancements of polymer nanocomposites in tribology. The influence of different types of nanofiller, such as carbon-based nanofiller, silicon-based nanofiller, metal oxide nanofiller and hybrid nanofiller, on the tribological performance of thermoplastic and thermoset nanocomposites is discussed. Since the tribological properties of polymer nanocomposites are not intrinsic but are dependent on sliding conditions, direct comparison between different types of nanofiller or the same nanofiller of different morphologies and structures is not feasible. Friction and wear rate are normalized to indicate relative improvement by different fillers. Emphasis is given to the effect of nanofiller content and surface modification of nanofillers on friction, wear resistance, wear mechanism and transfer film formation of its nanocomposites. Limitations from the previous works are addressed and future research on tribology of polymer nanocomposites is proposed.
