Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <sec id="ppap201300025-sec-0001" sec-type="section"> <p>In this work, we report on the synthesis of ethyl lactate‐based plasma polymer film (ELPPF) by plasma enhanced chemical vapour deposition (PECVD). Using a design of experiments, it appears that, among other, the injected power (<italic>P</italic>_RF) is the key parameter affecting the ELPPF features. Indeed, we observe a strong decrease of the COO‐C/H functionalities (from 12 to 2 at.%) within a limited <italic>P</italic>_RF domain. A more precise analysis of the film chemistry by combining XPS and chemical derivatization reveals that up to 95% of these carboxyl‐based functions are esters. On the other hand, we show that the cross‐linking degree of the ELPPF can be increased by a factor of two as a function of <italic>P</italic>_RF. This work paves the way for the tailoring of the barrier properties of ELPPF by controlling the ester content and the cross‐linking degree of the PPF.<inline-graphic xlink:href="ark:/27927/pgg3wjnb96t" content-type="ppap201300025-gra-0001" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </sec> </abstract>
