Title: Three-dimensional structure investigation of Waterborne Paint by Electron Microscopic Imaging

In this paper, the three-dimensional (3D) spatial structure of a TiO 2 coated waterborne paint film has been successfully investigated by serial block-face scanning electron microscopy (SBFSEM). The investigation clearly shows the spatial distribution of the TiO2 particles in the paint film and illustrates the degree of dispersion of the particles in the composite material. More than 58% of the volume of the TiO 2 particles are between 1.0 × 10 6 nm 3 to 1.0 × 10 7 nm 3 and the minimum distance between different particles can be detected is 124 nm. Different types of voids can be found in the 3D image of the cured water-borne paint film: voids that exist in the paint itself, voids produced by particle shedding, water evaporating and particles stacking. Among these voids, the ones produced by particle shedding is a cutting artefact. The research provides a different approach to clearly present the 3D spatial structure of paints and can clearly illustrate different kinds of voids inside the water-borne paint. While the resulting 3D structure of the paint, especially the different voids are important for further systematic research on the relationships between the spatial microstructure and the physical and chemical properties ofmore » the water-borne paint.« less
