The surface layer (SL) modification of polymeric materials is mainly carried out to improve wettability and adhesive properties and to increase surface cleanliness. TPS was modified in an air atmosphere under either atmospheric or reduced pressure. The process parameters for modifying the SL of TPS were determined based on wettability assessment using a goniometer, geometric structure using scanning electron microscopy (SEM), and the degree of oxidation (O\/C ratio) using X-ray photoelectron spectroscopy (XPS). Additionally, the effect of plasma treatment on TPS film sterilization was investigated.<\/jats:p>","DOI":"10.3390\/ma18092156","type":"journal-article","created":{"date-parts":[[2025,5,7]],"date-time":"2025-05-07T08:20:53Z","timestamp":1746606053000},"page":"2156","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Plasma Modification Effects of Thermoplastic Starch (TPS) Surface Layer: Film Wettability and Sterilization"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9728-5633","authenticated-orcid":false,"given":"Magdalena","family":"Stepczy\u0144ska","sequence":"first","affiliation":[{"name":"Department of Materials Engineering, Kazimierz Wielki University, Chodkiewicza 30, 85-064 Bydgoszcz, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aleksandra","family":"\u015apionek","sequence":"additional","affiliation":[{"name":"Department of Materials Engineering, Kazimierz Wielki University, Chodkiewicza 30, 85-064 Bydgoszcz, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,5,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e12447","DOI":"10.1111\/jfpe.12447","article-title":"Thermoplastic Starch: A Possible Biodegradable Food Packaging Material\u2014A Review","volume":"40","author":"Khan","year":"2017","journal-title":"J.
