Abstract
Superhydrophobic and transparent coatings are deposited
onto paper
by spraying alcohol suspensions of SiO<sub>2</sub> nanoparticles.
Superhydrophobicity depends on the aggregation states of nanoparticles,
which are determined by the type of alcohol used in the suspensions.
The superhydrophobicity of the paper is maintained after touching
the paper with a bare finger
