Comparison of NPIII and DBD Plasma Treatment in Terms of Wettability of PTFE and PA6
2016
We compared the effect of nitrogen plasma immersion ion implantation and dielectric barrier discharge
surface treatment on the wettability of two engineering polymers: PTFE and PA6. We found that NPIII is capable to
make the surface either hydrophilic or superhydrophobic depending on the operating parameters (fluence and voltage).
DBD plasma treatment effectively decreased the water contact angle of both types of polymer. However, while the
lowest value of water contact angle was reached within a few seconds for PA6, it took more than 5 minutes for PTFE.
