beam deposition method at different gas pressures (in English)

Summary

Polytetrafluoroethylene (PTFE) coatings were manufactured using the pulsed electron beam deposition (PED) technique. The presence of a PTFE structure was confirmed by means of Fourier transform infrared spectrometry (FT-IR). The surface morphology and roughness were characterized by atomic force microscopy (AFM). A pressure increase leads to a decrease in the material transport from the target to the substrate. The water contact angle (WCA) and surface free energy (SFE) were examined. The hydrophobic properties were preserved after film deposition.
