    Abstract

    Foam coating technique has shown to be a promising method for applying a thin pigment layer of nanoparticles on a paper web. The interest in applying a low coat weight coating layer is to create new functional surfaces using small amounts of new, typically expensive nanoparticles. The characterisation of thin pigment layer properties is more demanding than analysing traditional pigment coatings layers because of the low layer thickness of 1 µm or less with a coat weight of between 0.3 and 2 g/m2. This characterisation requires surface sensitive measuring techniques and a combination of different microscopic and spectroscopic surface analyses. In this study, the pigment layer structure and chemical properties of nanosilica-coated paper were analysed. The results were utilised in the development of the foam coating process
