Thus, in this study, atmospheric plasma as a pre-treatment was combined with a UV grafting process to obtain a durable surface modification on polyethylene terephthalate (PET). The most promising conditions for the atmospheric plasma process were found to be 15 kW power and 4 m\/min speed, leading to a contact angle reduction from 70 \u00b1 6\u00b0 to approximately 30\u00b0. However, it was observed that these values increased over time due to the ageing and washing of the PET surface, ultimately causing it to recover its initial contact angle. Therefore, the plasma-pre-treated PET samples were further modified through a UV grafting process using sodium acrylate (NaAc) and 3-sulfopropyl acrylate potassium salts (KAc). The grafted acrylate PET samples exhibited contact angles of 8 \u00b1 3\u00b0 and 28 \u00b1 13\u00b0 for NaAc and KAc, respectively, while showing durability in ageing and washing tests. The dry film thicknesses for both samples were found to be 28 \u00b1 2 \u03bcm. Finally, the anti-adhesive properties of the NaAc- and KAc-treated surfaces were evaluated using an Escherichia coli expressing YadA, an adhesive protein from Yersinia. The modified PET surfaces were highly effective in reducing bacterial adhesion by more than 90%.<\/jats:p>","DOI":"10.3390\/coatings13040715","type":"journal-article","created":{"date-parts":[[2023,3,31]],"date-time":"2023-03-31T11:32:28Z","timestamp":1680262348000},"page":"715","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Atmospheric Plasma and UV Polymerisation for Developing Sustainable Anti-Adhesive Polyethylene Terephthalate (PET) Surfaces"],"prefix":"10.3390","volume":"13","author":[{"given":"Tugce","family":"Caykara","sequence":"first","affiliation":[{"name":"CeNTI\u2014Centre for Nanotechnology and Smart Materials, 4760-034 Vila Nova de Famalic\u00e3o, Portugal"},{"name":"CEB\u2014Centre of Biological Engineering, School of Chemical and Biological Engineering, Universidade do Minho, 4710-057 Braga, Portugal"}]},{"given":"Sara","family":"Fernandes","sequence":"additional","affiliation":[{"name":"CeNTI\u2014Centre for Nanotechnology and Smart Materials, 4760-034 Vila Nova de Famalic\u00e3o, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7432-0726","authenticated-orcid":false,"given":"Adelaide","family":"Braga","sequence":"additional","affiliation":[{"name":"CEB\u2014Centre of Biological Engineering, School of Chemical and Biological Engineering, Universidade do Minho, 4710-057 Braga, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3217-2320","authenticated-orcid":false,"given":"Joana","family":"Rodrigues","sequence":"additional","affiliation":[{"name":"CEB\u2014Centre of Biological Engineering, School of Chemical and Biological Engineering, Universidade do Minho, 4710-057 Braga, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9265-0630","authenticated-orcid":false,"given":"Ligia Raquel","family":"Rodrigues","sequence":"additional","affiliation":[{"name":"CEB\u2014Centre of Biological Engineering, School of Chemical and Biological Engineering, Universidade do Minho, 4710-057 Braga, Portugal"}]},{"given":"Carla Joana","family":"Silva","sequence":"additional","affiliation":[{"name":"CeNTI\u2014Centre for Nanotechnology and Smart Materials, 4760-034 Vila Nova de Famalic\u00e3o, Portugal"},{"name":"CITEVE\u2014Portuguese Technological Centre for the Textile and Clothing Industries, Department of Chemical and Biotechnology, 4760-034 Vila Nova de Famalic\u00e3o, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1800516","DOI":"10.2807\/1560-7917.ES.2018.23.46.1800516","article-title":"Prevalence of healthcare-associated infections, estimated incidence and composite antimicrobial resistance index in acute care hospitals and long-term care facilities: Results from two european point prevalence surveys, 2016 to 2017","volume":"23","author":"Suetens","year":"2018","journal-title":"Eurosurveillance"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"363","DOI":"10.1007\/s00430-020-00660-8","article-title":"Exploring the potential of polyethylene terephthalate in the design of antibacterial surfaces","volume":"209","author":"Sande","year":"2020","journal-title":"Med.
