Abstract
Foam coating is 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
arises from the need 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
pigmented coatings layers because of the low coat weight
(0.3-2.0 g/m2) and a corresponding low layer thickness of
1 µm or less. 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
