Considering that valuable artworks always suffer from intolerance of harsh conditions and water impact caused
by the intrinsic hydrophilicity of commercial pigments, pigments possessing anti-fouling performance, environmental
durability and chemical stability have considerable significance for minimizing the deteriorations of
painted artworks and furthermore promoting cultural communications between different regions. Herein, we
have synthesized a series of colorful pigments which exhibit excellent durability in high temperature and humidity
environment, long-term UV-light irradiation, underwater immersion and corrosion of chemical solutions.
The superhydrophobicity of as-prepared pigments endues painted artworks with superior anti-fouling performance
towards multiple liquids including water, orange juice, coffee, tea, milk and cola. Both of the colors and
hierarchical structures of synthesized pigments are in-situ formed during hydrothermal process without any
addition of organic dyes. In virtue of their substrate-independency, these superhydrophobic pigments are userfriendly
and could be applied on both 3D and 2D substrates just like the manner of commercial pigments.
