Tests were done at temperatures between the ambient temperature and the glass transition temperature ( T<jats:sub>g<\/jats:sub>[Formula: see text] of the adhesive. Using a metal mold, cured plates of the neat and RGO reinforced epoxy adhesive were prepared. The adhesive powder and the bulk dumbbell-shaped specimens, obtained from cured adhesive plates, were subjected to differential scanning calorimetry (DSC) and tensile tests, respectively, to obtain the T<jats:sub>g<\/jats:sub> as well as mechanical properties of the adhesives. The results indicated that adding RGO up to 0.5\u2009wt% increased the glass transition temperature, the modulus of elasticity, and the strength of the adhesive. It was found that the presence of RGO reduced the adhesive\u2019s strain at the break at the ambient temperature. However, at high temperatures, near the T<jats:sub>g<\/jats:sub>, the ultimate strain of RGO-reinforced adhesives decreased slightly when compared to the ultimate strain of the neat specimens. This explains the reduction in toughness at ambient temperature obtained by adding RGO and the increase at high temperatures. Finally, the failure morphology of the neat and RGO-reinforced adhesive specimens was investigated using microscopic imaging of the specimens\u2019 failure cross-sections, which supported and justified the experimental observations. <\/jats:p>","DOI":"10.1177\/00219983211031659","type":"journal-article","created":{"date-parts":[[2021,7,9]],"date-time":"2021-07-09T05:26:57Z","timestamp":1625808417000},"page":"3839-3848","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":21,"title":["Effect of reduced graphene oxide on mechanical behavior of an epoxy adhesive in glassy and rubbery states"],"prefix":"10.1177","volume":"55","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9101-6785","authenticated-orcid":false,"given":"Ata","family":"Khabaz-Aghdam","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering, Sahand University of Technology, Iran"},{"name":"Instituto de Ci\u00eancia e Inova\u00e7\u00e3o em Engenharia Mec\u00e2nica e Engenharia Industrial (INEGI), Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9095-6994","authenticated-orcid":false,"given":"Bashir","family":"Behjat","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Sahand University of Technology, Iran"}]},{"given":"EAS","family":"Marques","sequence":"additional","affiliation":[{"name":"Instituto de Ci\u00eancia e Inova\u00e7\u00e3o em Engenharia Mec\u00e2nica e Engenharia Industrial (INEGI), Portugal"}]},{"given":"RJC","family":"Carbas","sequence":"additional","affiliation":[{"name":"Instituto de Ci\u00eancia e Inova\u00e7\u00e3o em Engenharia Mec\u00e2nica e Engenharia Industrial (INEGI), Portugal"}]},{"given":"Lucas FM da","family":"Silva","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Faculty of Engineering, University of Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6681-7679","authenticated-orcid":false,"given":"H","family":"Roghani-Mamaqani","sequence":"additional","affiliation":[{"name":"Faculty of Polymer Engineering, Sahand University of Technology, Iran"}]}],"member":"179","published-online":{"date-parts":[[2021,7,8]]},"reference":[{"key":"bibr1-00219983211031659","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-319-55411-2"},{"key":"bibr2-00219983211031659","doi-asserted-by":"publisher","DOI":"10.1557\/JMR.1993.1185"},{"key":"bibr3-00219983211031659","doi-asserted-by":"publisher","DOI":"10.1080\/00218464.2018.1452736"},{"key":"bibr4-00219983211031659","first-page":"1","volume":"2010","author":"Prolongo SG","year":"2010","journal-title":"Nanotechnol Nanomater"},{"key":"bibr5-00219983211031659","doi-asserted-by":"publisher","DOI":"10.1126\/science.1102896"},{"key":"bibr6-00219983211031659","doi-asserted-by":"publisher","DOI":"10.1002\/adma.201001068"},{"key":"bibr7-00219983211031659","doi-asserted-by":"publisher","DOI":"10.1002\/pen.23292"},{"key":"bibr8-00219983211031659","doi-asserted-by":"publisher","DOI":"10.1166\/sam.2013.1453"},{"key":"bibr9-00219983211031659","doi-asserted-by":"publisher","DOI":"10.1016\/j.polymer.2013.08.026"},{"key":"bibr10-00219983211031659","doi-asserted-by":"publisher","DOI":"10.1039\/b915228h"},{"key":"bibr11-00219983211031659","doi-asserted-by":"publisher","DOI":"10.1177\/0021998314522674"},{"key":"bibr12-00219983211031659","doi-asserted-by":"publisher","DOI":"10.1016\/j.compositesa.2013.05.017"},{"key":"bibr13-00219983211031659","doi-asserted-by":"publisher","DOI":"10.1002\/adfm.201103041"},{"key":"bibr14-00219983211031659","doi-asserted-by":"publisher","DOI":"10.1002\/pi.4763"},{"key":"bibr15-00219983211031659","doi-asserted-by":"publisher","DOI":"10.1038\/srep02086"},{"key":"bibr16-00219983211031659","doi-asserted-by":"publisher","DOI":"10.1038\/srep04375"},{"key":"bibr17-00219983211031659","doi-asserted-by":"publisher","DOI":"10.1016\/j.apsusc.2014.07.159"},{"key":"bibr18-00219983211031659","doi-asserted-by":"publisher","DOI":"10.1039\/c1jm11434d"},{"key":"bibr19-00219983211031659","doi-asserted-by":"publisher","DOI":"10.1088\/0957-4484\/25\/12\/125707"},{"key":"bibr20-00219983211031659","doi-asserted-by":"publisher","DOI":"10.1177\/0021998319895806"},{"key":"bibr21-00219983211031659","doi-asserted-by":"publisher","DOI":"10.1080\/00218464.2020.1742114"},{"key":"bibr22-00219983211031659","doi-asserted-by":"publisher","DOI":"10.1007\/s10443-016-9559-3"},{"key":"bibr23-00219983211031659","unstructured":"Saint-Denis La Plaine.
