Abstract
Nanocharacterization techniques such as nanoindentation and atomic force microscopy
were used to investigate the exterior durability of waterborne coatings improved with
inorganic nanosized UV-absorbers. Nanocomposite coatings for exterior uses of wood were
formulated with different type of nanoparticles and their performance was evaluated
trough artificial aging. Nanoindentation in continuous stiffness mode was used to demonstrate
the changes of hardness and Young’s modulus of the coatings after accelerated
weathering. The degradation mechanism of the surface coatings was investigated with
atomic force microscopy that has provided valuable information on the morphological
and microstructural changes of the surface coatings with the artificial aging. Additionally,
the glass transition temperature and optical appearance changes were reported. The results
obtained have shown that the nanoindentation technique in conjunction with atomic force
microscopy can be satisfactorily used for durability investigation and service life prediction
of nanocomposite coatings for wood.
