In this work, graphene oxide (GO) was used as a multifunctional additive in epoxy coatings to improve these properties. Owing to its two-dimensional sheet-like nanostructure and abundant oxygen-containing functional groups, which enable a favorable interface with the epoxy matrix, incorporating GO into epoxy coatings endows the coating with multiple enhanced performances, including anti-corrosion performance, UV resistance, wear resistance, and adhesion to metal substrates. The resulting GO\/EP composite coating exhibits higher adhesion strength (15.08 MPa) than that of neat epoxy coating (12.02 MPa), and delivers excellent corrosion resistance, with a corrosion current density of 4.69 \u00d7 10\u221211 A\u00b7cm\u22122 which is as low as 1\/3 that of the neat epoxy coating after 25 days of immersion in NaCl solution. Notably, after multiple cycles of thermal cycling testing, the coating maintains an impedance ~40 times higher than that of neat epoxy coating. After UV aging testing, comparing to neat EP coating, the GO\/EP coating experiences far less degradation in gloss, water resistance, corrosion resistance and bonding strength to steel substrates. In addition, tribological tests confirmed that GO\/EP has improved wear resistance compared with neat epoxy coating and the wear rate of epoxy coating was reduced by ~30% with incorporation of only 0.1%wt GO. This study provides a promising strategy for developing durable protective coatings for practical applications.<\/jats:p>","DOI":"10.3390\/nano16191275","type":"journal-article","created":{"date-parts":[[2026,10,8]],"date-time":"2026-10-08T15:16:52Z","timestamp":1791472612000},"page":"1275","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Facile Enhancement of Corrosion, Wear and UV Aging Resistance of Epoxy Composite Coatings via Graphene Oxide Incorporation"],"prefix":"10.3390","volume":"16","author":[{"given":"Fujun","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Civil Engineering, Lanzhou Jiaotong University, Lanzhou 730070, China"},{"name":"Gansu Changda Highway Co., Ltd., Lanzhou 730000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Boyi","family":"Qiu","sequence":"additional","affiliation":[{"name":"Institute of Advanced Wear & Corrosion Resistant and Functional Materials, Jinan University, Guangzhou 510632, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5244-862X","authenticated-orcid":false,"given":"Xusheng","family":"Du","sequence":"additional","affiliation":[{"name":"Institute of Advanced Wear & Corrosion Resistant and Functional Materials, Jinan University, Guangzhou 510632, China"},{"name":"National Joint Engineering Research Center of High Performance Metal Wear Resistant Materials Technology, Jinan University, Guangzhou 510632, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,10,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.cja.2023.04.016","article-title":"Corrosion and aging of organic aviation coatings: A review","volume":"36","author":"Zhang","year":"2023","journal-title":"Chin.
