20.500.12556/DKUM-93252 Non-equilibrium plasma methods for tailoring surface properties of polyvinylidene fluoride review and challenges Modification and functionalization of polymer surface properties is desired in numerous applications, and a standard technique is a treatment with non-equilibrium gaseous plasma. Fluorinated polymers exhibit specific properties and are regarded as difficult to functionalize with polar functional groups. Plasma methods for functionalization of polyvinylidene fluoride (PVDF) are reviewed and different mechanisms involved in the surface modification are presented and explained by the interaction of various reactive species and far ultraviolet radiation. Most authors used argon plasma but reported various results. The discrepancy between the reported results is explained by peculiarities of the experimental systems and illustrated by three mechanisms. More versatile reaction mechanisms were reported by authors who used oxygen plasma for surface modification of PVDF, while plasma sustained in other gases was rarely used. The results reported by various authors are analyzed, and correlations are drawn where feasible. The processing parameters reported by different authors were the gas pressure and purity, the discharge configuration and power, while the surface finish was predominantly determined by X-ray photoelectron spectroscopy (XPS) and static water contact angle (WCA). A reasonably good correlation was found between the surface wettability as probed by WCA and the oxygen concentration as probed by XPS, but there is hardly any correlation between the discharge parameters and the wettability. polyvinylidene fluoride gaseous plasma surface modification wettability functionalization activation plazma raziskovanje plazme plinska plazma površinska modifikacija metode poliviniliden fluorid true false true MDPI Angleški jezik Slovenski jezik https://www.mdpi.com/journal/polymers © 2021 by the authors Članek v reviji 2025-06-16 10:58:33 2025-06-16 10:58:33 2025-06-17 03:09:18 0000-00-00 00:00:00 2021 0 0 str. 4243-1-4243-19 no. 23 Vol. 13 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2021-11-15 2021-12-02 2021-12-03 53 88669443 10.3390/polym13234243 2073-4360 polymers-13-04243.pdf polymers-13-04243.pdf 1 5C889216830EDA4BBA01A43CCCF88121 112d0d1c3a1ebf7ca28f63b214facefc9969f750d03e9d669c7f717c24eea73d b49b0644-4a90-11f0-a2f6-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=192246 https://www.mdpi.com/2073-4360/13/23/4243 0 b9836aca-4a90-11f0-a2f6-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=192247 Fakulteta za elektrotehniko, računalništvo in informatiko 0 0 0
