20.500.12556/DiRROS-16295 Deposition of chitosan on plasma-treated polymers a review Deposition of chitosan on plasma-treated polymers—a review Materials for biomedical applications often need to be coated to enhance their performance, such as their biocompatibility, antibacterial, antioxidant, and anti-inflammatory properties, or to assist the regeneration process and influence cell adhesion. Among naturally available substances, chitosan meets the above criteria. Most synthetic polymer materials do not enable the immobilization of the chitosan film. Therefore, their surface should be altered to ensure the interaction between the surface functional groups and the amino or hydroxyl groups in the chitosan chain. Plasma treatment can provide an effective solution to this problem. This work aims to review plasma methods for surface modification of polymers for improved chitosan immobilization. The obtained surface finish is explained in view of the different mechanisms involved in treating polymers with reactive plasma species. The reviewed literature showed that researchers usually use two different approaches: direct immobilization of chitosan on the plasma-treated surface or indirect immobilization by additional chemistry and coupling agents, which are also reviewed. Although plasma treatment leads to remarkably improved surface wettability, this was not the case for chitosan-coated samples, where a wide range of wettability was reported ranging from almost superhydrophilic to hydrophobic, which may have a negative effect on the formation of chitosan-based hydrogels. polymer surfaces chitosan coatings plasma-surface modification adhesion polimerne površine hitozan prevleke plazemska modifikacija površin adhezija true false true MDPI Švica Angleški jezik Slovenski jezik © 2023 by the author Neznano 2023-02-24 15:04:24 2023-02-24 15:04:26 2023-02-25 03:41:57 0000-00-00 00:00:00 2023 0 0 Nasl. z nasl. zaslona; Opis vira z dne 24. 2. 2023; str. 1-26 iss. 5, [article no] 1109 Vol. 15 Mar. 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 2023-02-21 2023-02-23 620.1/.2 2073-4360 143072259 https://www.mdpi.com/2073-4360/15/5/1109 1 c3949921-b443-11ed-b359-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=21738 polymers-15-01109.pdf polymers-15-01109.pdf 1 0714D3ED84D923D1D8B77C1D95C99201 d2f3719fefe6bbfb5683b62b6d0aa495bd8b372bf0b26b6cb9e36359a0612246 6aef6435-b444-11ed-b359-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=21739 Institut Jožef Stefan 0 0 0
