20.500.12556/DKUM-92261 Obtaining medical textiles based on viscose and chitosan/zinc nanoparticles with improved antibacterial properties by using a dielectric barrier discharge This study aimed to obtain functional viscose textiles based on chitosan coatings with improved antibacterial properties and washing durability. For that reason, before functionalization with chitosan/zinc nanoparticles (NCH+Zn), the viscose fabric was modified by nonthermal gas plasma of dielectric barrier discharge (DBD) to introduce into its structure functional groups suitable for attachment of NCH+Zn. NCH+Zn were characterized by measurements of hydrodynamic diameter and zeta potential and AFM. DBD-plasma-modified and NCH+Zn-functionalized fabrics were characterized by zeta potential measurements, ATR-FTIR spectroscopy, the calcium acetate method (determination of content of carboxyl and aldehyde groups), SEM, breaking-strength measurements, elemental analysis, and ICP-OES. Their antibacterial activity was determined under dynamic contact conditions. In addition to SEM, the NCH+Zn distributions on viscose fabrics were also indirectly characterized by measuring their absorbent capacities before and after functionalization with NCH+Zn. Washing durability was monitored through changes in the zeta potential, chitosan and zinc content, and antibacterial activity after 1, 3, and 5 washing cycles. The obtained results showed that DBD plasma modification contributed to the simultaneous improvement of NCH+Zn sorption and antibacterial properties of the viscose fabric functionalized with NCH+Zn, and its washing durability, making it suitable for the production of high-value-added medical textiles. medical textiles antibacterial properties viscose chitosan/zinc nanoparticles dielectric barrier discharge medicinske tekstilije antibakterijske lastnosti viskoza hitozan cink nanodelci dielektrična barierna razelektritev true false true MDPI AG Angleški jezik Slovenski jezik https://www.mdpi.com/journal/polymers © 2022 by the authors Članek v reviji 2025-03-26 09:17:07 2025-03-26 09:18:06 2025-03-27 03:11:51 0000-00-00 00:00:00 2022 0 0 str. 1-16 iss. 19 (4152) Vol. 14 Oct. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2022-09-20 2022-09-30 2022-10-04 677.017:61 124770819 10.3390/polym14194152 2073-4360 polymers-14-04152.pdf polymers-14-04152.pdf 1 E8349A49FDCCE75B963797E1A122F346 a030a2f1ee99123771183d86adeb81c470cba52d84ea61ff95279c3b8e4090a9 0557ecc3-0a1c-11f0-af23-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=189660 https://www.mdpi.com/2073-4360/14/19/4152 1 da8c974a-0a1a-11f0-af23-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=189659 Fakulteta za strojništvo 0 0 0
