Résumé : 2,2,4,4,6,8,8-Heptamethylnonane (HMN), a saturated branched hydrocarbon precursor, is deposited by means of atmospheric plasma DBD. Hydrophobic coatings starting from this precursor which is liquid at room temperature can be obtained. The degree of polymerization of the coating seems to be dependent on the amount of provided precursor. The coatings were characterized by FTIR, TOF-SIMS, WCA, SE, and XPS. The plasma deposition of the liquid, highly branched saturated precursor 2,2,4,4,6,8,8-heptamethylnonane (HMN) by means of an atmospheric pressure dielectric barrier is reported. The obtained coatings are hydrophobic and the chemical structure suggests a low fragmentation of the precursor. Increasing the amount of precursor not only favors the deposition rate but also seems to favor a better crosslinking in the deposited coating. Copyright © 2013 WILEY-VCH Verlag GmbH & Co.
