This review presents the state of the art regarding the improvement of scratch resistance of polymeric coatings. In particular, our attention is focused on the effect of inorganic nanometric fillers on the scratch resistance of organic coatings. Two main strategies are described for the achievement of such nanostructured hybrid organic/inorganic coatings: either a top‐down or a bottom‐up approach. The current state of the art of improving the scratch resistance of polymeric coatings is reported. To achieve nanostructured organic/inorganic hybrid coatings, either a top‐down or a bottom‐up approach can be followed. The top‐down approach includes dispersion of a wide range of different metal‐oxide particles in the polymeric matrix. Alternatively, the bottom‐up in situ formation of the inorganic domain has been shown to be very appealing in order to obtain a good distribution of the inorganic phase within the polymer matrix.
