Figure 3. (A, Movie S1) Coated and uncoated sections of a wall
that are exposed to dyed water. (B, Movie S2) The oil-based ink traces
on the coated section of the wall readily contracted and they could be
easily wiped away with dry tissues. (C, Movie S3) 3M tape readily fell
from the coated section of the wall by the action of its own weight,
while strongly adhering to the uncoated section of the wall.
Finally, in order to evaluate the on-site use of the coating on
large-area substrates, we applied our coatings on different building
walls (lime and ceramic tile walls) and exposed them to splashes of
water, graffiti, and adhesive tapes. As anticipated, outstanding
self-cleaning and anti-graffiti performance was achieved, and the tapes
could be readily removed from the coated walls (Fig. 3A-C, Movies
Si-S3).
