| مستخلص: |
The electrophoretic deposition of multi‐walled carbon nanotubes (MWCNTs) has been well‐researched; however, preparatory steps lead to MWCNT coating contamination and deposits often have weak adhesion to the substrate. This work targets these two weaknesses. First, MWCNTs were functionalized by nonthermal, radiofrequency plasma, producing oxygenated MWCNTs (O‐MWCNTs), with which water‐based suspensions were prepared. Second, an ethane‐based plasma polymer was applied on the metallic substrate as an interlayer to improve coating adhesion. O‐MWCNT coatings were produced at 5–40 V for 1–60 min. Homogeneous coatings with thicknesses up to 10 µm were achieved, the composition was 90‐95 at% carbon with the balance element being oxygen, and coating adhesion without damage was confirmed for shear stresses up to 16 Pa.
