Waterproof Filter Paper

Polymerization technique yields superhydrophobic cellulose surfaces
Department: Science & Technology

In work aimed at developing superhydrophobic biofiber surfaces, polymer scientists in Sweden have shown that filter paper can be turned into a water-resistant, self-cleaning material. Water droplets roll off the surface of the paper, carrying dirt with them (Chem. Commun., 2006, 3594).

The research paper describes a facile way to transform a very hydrophilic substrate into an extremely hydrophobic one. "To the best of our knowledge, this is the first example of a superhydrophobic cellulose . . .
