Despite significant efforts, the longevity of UHMWPE implants is still impaired due to their compromised tribological performance, leading to osteolysis and aseptic loosening. The present study aims to critically evaluate and analyze the tribological performance, of the next generation acetabular liner material, that is, a chemically modified graphene oxide (GO) reinforced HDPE\/UHMWPE (HU) bionanocomposite (HUmGO), against stainless steel (SS 316L) counterface in lubricated conditions. This work also provides a performance comparative assessment of HUmGO with respect to medical grades, UHMWPE (UC) and crosslinked UHMWPE (XL-UC). Significant attempts have been made to correlate the tribological properties (frictional behavior, wear rate, wear debris shape and size, wear mechanism) with the physicomechanical conditions (contact stresses) at sliding contact and the variation in molecular architecture of different UHMWPE materials. Additionally, an emphasis is put forward to critically anlyze the nature of lubrication regime based on the bearing characterstic parameters. HUmGO exhibited a lower COF (0.07) and specific wear rate (2.86 \u00d7 10\n                    <jats:sup>\u22128\u00a0<\/jats:sup>\n                    mm\n                    <jats:sup>3<\/jats:sup>\n                    \/Nm) than UC and XL-UC under identical sliding conditions. The worn surfaces on HUmGO revealed the signatures of less abrasive wear and limited deformation. Based on the estimated lambda (\u03bb) ratio and Sommerfield number, all the investigated sliding contacts exhibited boundary lubrication. Taken together, the modified GO reinforced HDPE\/UHMWPE bionanocomposite can be considered as a new generation biomaterial for the fabrication of acetabular liner for hip-joint prosthesis .\n                  <\/jats:p>","DOI":"10.1177\/08853282221085633","type":"journal-article","created":{"date-parts":[[2022,5,3]],"date-time":"2022-05-03T09:38:50Z","timestamp":1651570730000},"page":"204-218","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":11,"title":["Probing lubricated sliding wear properties of HDPE\/UHMWPE hybrid bionanocomposite"],"prefix":"10.1177","volume":"37","author":[{"given":"Vidushi","family":"Sharma","sequence":"first","affiliation":[{"name":"Laboratory for Biomaterials, Materials Research Centre, Indian Institute of Science, Bangalore, India"},{"name":"Centre of Excellence for Dental and Orthopedic Applications, Material Research Centre, Indian Institute of Science, Bangalore, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rajeev K","family":"Gupta","sequence":"additional","affiliation":[{"name":"Surface Interaction and Manufacturing Laboratory, Department of Mechanical Engineering, Indian Institute of Science, Bangalore, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Satish V","family":"Kailas","sequence":"additional","affiliation":[{"name":"Surface Interaction and Manufacturing Laboratory, Department of Mechanical Engineering, Indian Institute of Science, Bangalore, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7303-7248","authenticated-orcid":false,"given":"Bikramjit","family":"Basu","sequence":"additional","affiliation":[{"name":"Laboratory for Biomaterials, Materials Research Centre, Indian Institute of Science, Bangalore, India"},{"name":"Centre of Excellence for Dental and Orthopedic Applications, Material Research Centre, Indian Institute of Science, Bangalore, India"},{"name":"Centre for Biosystems Science and Engineering, Indian Institute of Science, Bangalore, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2022,5,3]]},"reference":[{"key":"bibr1-08853282221085633","doi-asserted-by":"publisher","DOI":"10.4081\/or.2011.e16"},{"key":"bibr2-08853282221085633","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-319-98596-1_1"},{"key":"bibr3-08853282221085633","doi-asserted-by":"publisher","DOI":"10.3109\/17453679408993734"},{"key":"bibr4-08853282221085633","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-319-12478-0_5"},{"key":"bibr5-08853282221085633","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmbbm.2008.12.006"},{"key":"bibr6-08853282221085633","doi-asserted-by":"publisher","DOI":"10.3390\/polym12020323"},{"key":"bibr7-08853282221085633","doi-asserted-by":"publisher","DOI":"10.1016\/B978-0-323-35401-1.00029-6"},{"key":"bibr8-08853282221085633","first-page":"1","volume":"34","author":"Pietrzak WS","year":"2019","journal-title":"J Invest Surg"},{"key":"bibr9-08853282221085633","doi-asserted-by":"publisher","DOI":"10.1007\/s00402-011-1340-3"},{"key":"bibr10-08853282221085633","doi-asserted-by":"publisher","DOI":"10.1016\/j.biomaterials.2014.02.019"},{"key":"bibr11-08853282221085633","first-page":"1","volume":"34","author":"Shi J","year":"2019","journal-title":"J Invest Surg"},{"key":"bibr12-08853282221085633","doi-asserted-by":"publisher","DOI":"10.3390\/ma10070791"},{"key":"bibr13-08853282221085633","doi-asserted-by":"publisher","DOI":"10.1007\/s00264-010-1161-y"},{"key":"bibr14-08853282221085633","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-010-1717-6"},{"key":"bibr15-08853282221085633","doi-asserted-by":"publisher","DOI":"10.1016\/j.biomaterials.2003.12.048"},{"key":"bibr16-08853282221085633","doi-asserted-by":"publisher","DOI":"10.1016\/j.arth.2005.07.009"},{"key":"bibr17-08853282221085633","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmbbm.2014.06.013"},{"key":"bibr18-08853282221085633","doi-asserted-by":"publisher","DOI":"10.1016\/j.compositesb.2015.07.019"},{"key":"bibr19-08853282221085633","doi-asserted-by":"publisher","DOI":"10.1098\/rsif.2018.0273"},{"key":"bibr20-08853282221085633","doi-asserted-by":"publisher","DOI":"10.1021\/acsbiomaterials.9b01327"},{"key":"bibr21-08853282221085633","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmbbm.2020.104205"},{"key":"bibr22-08853282221085633","doi-asserted-by":"publisher","DOI":"10.1002\/jbm.b.31818"},{"key":"bibr23-08853282221085633","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmbbm.2011.09.008"},{"key":"bibr24-08853282221085633","doi-asserted-by":"publisher","DOI":"10.1016\/j.medengphy.2010.06.007"},{"key":"bibr25-08853282221085633","doi-asserted-by":"publisher","DOI":"10.1016\/0043-1648(95)06665-9"},{"key":"bibr26-08853282221085633","doi-asserted-by":"publisher","DOI":"10.1243\/0954408011530389"},{"key":"bibr27-08853282221085633","unstructured":"S.S.
