This data is used to create a representative volume element of the coating, which is then available for further simulations. These include simulations of the sorption and diffusion of gases through the coating in order to model the permeation processes. The model generated in this way is to be validated by varying parameters such as coating chemistry and structure, as well as the permeating gas, and comparing the prediction with measurement data. Finally, it will be checked which characterisation methods are relevant for the model and whether complex methods can be replaced by simpler methods. The findings from this project can be used, for example, to develop instruments for process monitoring and control in order to promote the industrial use of PECVD.<\/p>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary><strong>Project Data and Funding<\/strong><\/summary>\n<p class=\"wp-block-paragraph\">We would like to thank the DFG for funding the project (funding code542661390) and the project partners for their cooperation.<br><strong>Project Duration: <\/strong>&#8211;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Project Partners<\/strong><\/h2>\n\n\n<section id=\"logo-bar-block_8dd9123fbeddbecaa6a801056336b579\" class=\"block-logo-bar py-2xl  clear-both\">\n    <div class=\"theGridWrapper overflow-hidden  \">\n        <div class=\"grid grid-cols-[repeat(auto-fill,minmax(140px,1fr))] gap-base\">\n                            <figure class=\" relative h-full  \"><img decoding=\"async\" fetchpriority=\"low\"  class=\" object-contain w-full h-full mb-base  \"  src=\"https:\/\/ikv-aachen.de\/wp-content\/uploads\/2024\/12\/Logo-DFG.png\" srcset=\"https:\/\/ikv-aachen.de\/wp-content\/uploads\/2024\/12\/Logo-DFG-748x591.png 748w\" sizes=\"auto, (max-width: 748px) 100vw, 748px\" width=\"748\" height=\"591\" alt=\"Logo-DFG\" loading=\"lazy\" \/><\/figure>                                <\/div>\n    <\/div>\n<\/section>\n<\/details>\n\n\n\n<h2 class=\"wp-block-heading\">Keywords<\/h2>\n","protected":false},"excerpt":{"rendered":"<p>The PermaSim project investigates the mechanisms of gas permeation through PECVD barrier layers on a micro- and nanoscale level.
