The mechanisms and the underlying physics of 2D materials are reviewed with experimental results. This paper covers some of the widely investigated solid lubricants such as MoS2, graphene, and boron compounds, namely h-BN and boric acid. Solid lubricants such as black phosphorus that have gained research prominence are also discussed regarding their application as additives in polymeric materials. The effects of process conditions, film deposition parameters, and dopants concentration on friction and wear rate are discussed with a qualitative and quantitative emphasis that are supported with adequate examples and application areas and summarized in the form of graphs and tables for easy readability. The use of advanced manufacturing methods such as powder metallurgy and sintering to produce solid lubricants of superior tribological performance and the subsequent economic gain from their development as a substitute for liquid lubricant are also evaluated.<\/jats:p>","DOI":"10.3390\/ma14071630","type":"journal-article","created":{"date-parts":[[2021,3,26]],"date-time":"2021-03-26T13:17:53Z","timestamp":1616764673000},"page":"1630","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":116,"title":["Tribological Properties of 2D Materials and Composites\u2014A Review of Recent Advances"],"prefix":"10.3390","volume":"14","author":[{"given":"Bodhi R.","family":"Manu","sequence":"first","affiliation":[{"name":"Mechanical Industrial and Manufacturing Engineering (MIME) Department, University of Toledo, Toledo, OH 43606, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anju","family":"Gupta","sequence":"additional","affiliation":[{"name":"Mechanical Industrial and Manufacturing Engineering (MIME) Department, University of Toledo, Toledo, OH 43606, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahalapitiya H.","family":"Jayatissa","sequence":"additional","affiliation":[{"name":"Mechanical Industrial and Manufacturing Engineering (MIME) Department, University of Toledo, Toledo, OH 43606, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,3,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"58","DOI":"10.1016\/j.triboint.2013.02.003","article-title":"Global energy consumption due to friction in paper machines","volume":"62","author":"Holmberg","year":"2013","journal-title":"Tribol.
