Coatings, i.e. films that form on surfaces upon application of a formulation, are ubiquitous. In 2010, the global coatings market was worth > US$ 110 billion. The Swedish share is considerable since the country hosts some very strong industries, e.g. Bona AB. The market is huge, but, the competition is global. Staying competitive means inventing new and replacing established formulations by environmentally friendly, healthy and sustainable chemistries. To do this rationally and effectively, it is needed to understand how the composition of the original formulation and the deposition conditions affect the performance of the coating. However, so far it has not been possible to establish such a relationship.
It is expected that it would be easier to establish relationships between formulation composition and deposition conditions with the structure of the coatings at the nano and micro scale. This will in turn facilitate in a later step predicting their performance. In this project, with a focus on composite coatings, we aim at establishing a multi-methodological experimental approach for the characterization of different relevant nano/micro scale properties of the coatings. Then we will study how this properties depend on the composition of model formulations and on how these formulations are applied on surfaces. Finally, we will establish a connection between these aspects and different macro scale properties traditionally employed to predict the performance of a coating.
