Deposition of 2‐oxazoline‐based plasma polymer coatings using atmospheric pressure helium plasma jet

We report on the use of helium plasma jet for plasma polymerisation of 2‐methyl‐2‐oxazoline (OX) on heated silicon substrates. The X‐ray photo electron spectroscopy (XPS) characterisation shows a substantial improvement in film stability in buffer solution when depositing at temperatures above 50°C. Principal component analysis of the time‐of‐flight–secondary ion mass spectrometry data shows excellent correlation with the XPS results, providing...
