Methoden voor het meten van de dikte van aluminiumcoatings

The production of barrier packaging materials, e.g., for food, by physical vapor deposition of inorganic coatings such as aluminum on polymer substrates is an established and well understood functionalization technique today. In order to achieve a sufficient barrier against gases, a coating thickness of approximately 40 nm aluminum is necessary. In an article published in Coatings, researchers at the Fraunhofer-Institute for Process Engineering and Packaging IVV in Germany provide an overview of relevant methods for determining the aluminum coating thickness. Theoretical background, explanation of methods, analysis and effects on measured values, limitations, and resolutions are provided.
