Optical diagnostics and mass spectrometry on the afterglow of an atmospheric pressure Ar/O radiofrequency plasma used for polymer surface treatment
Corinne Y. Duluard, Thierry Dufour, Julie Hubert +1
In the context of polymer surface treatment, the afterglow of an atmospheric pressure Ar/O radiofrequency plasma is characterized by optical emission spectroscopy, laser induce…
Chemical mechanisms inducing a dc current measured in the flowing post-discharge of an RF He-O2 plasma torch
Thierry Dufour, J Hubert, N Vandencasteele +1
The post-discharge of an RF plasma torch supplied with helium and oxygen gases is characterized by mass spectrometry, optical emission spectroscopy and electrical measurements. We…
Etching Processes of Polytetrafluoroethylene Surfaces Exposed to He and He-O2 Atmospheric Post-discharges
J Hubert, Thierry Dufour, Nicolas Vandencasteele +3
A comparative study of polytetrafluoroethylene (PTFE) surfaces treated by the post-discharge of He and He-O2 plasmas at atmospheric pressure is presented. The characterization of t…
Chemical and Physical Effects of the Carrier Gas on the Atmospheric Pressure PECVD of Fluorinated Precursors
Julie Hubert, Nicolas Vandencasteele, Jérémy Mertens +6
The atmospheric pressure PECVD deposition and texturization of hydrophobic coatings using liquid fluorinated C6F12 and C6F14 precursors are investigated. The effect of the carrier…
Influence of ambient air on the flowing afterglow of an atmospheric pressure Ar/O2 radiofrequency plasma
C. Y. Duluard, Thierry Dufour, J Hubert +1
The influence of ambient air on the flowing afterglow of an atmospheric pressure Ar/O2 radiofrequency plasma has been investigated experimentally. Spatially resolved mass spectrome…
Synthesis and texturization processes of (super)-hydrophobic fluorinated surfaces by atmospheric plasma
Julie Hubert, Jérémy Mertens, Thierry Dufour +6
