Facile Method to Prepare Superhydrophobic and Water Repellent Cellulosic Paper

Figure 4

(a) The easy/self-cleaning process on a water-repellent surface of a siloxane-particle film on paper is demonstrated in the successive snapshots. The film surface was intentionally contaminated with reddish particles which were removed by water. (b) The same process was repeated on a hydrophobic siloxane film on paper. The treated paper was stained by the red particles, upon water flow.
