Re: Super-Durable Material Made from Wood Waste is Stronger, Cheaper, and Lighte...

Ah, article answers my speculative question.

"Of course, CNC is not perfect – it’s biggest drawback lies in how it deals
with water.  While the hydrogen bonds between the molecules are too strong
to simply be dissolved by H2O, the cellulose can become disordered when
wet.  Since hydrogen bonds with water, a drop can potentially turn CNC into
a water-loving substance, soaking up the stuff like a paper towel.  This
could reduce the strength and greatly increase the weight of the CNC while
jostling its microscopic make-up. Researchers exploring ways to develop CNC
are striving to overcome its shortcomings with moisture by either adding it
to devices that do not come in contact with water, or altering its surface
chemistry to repel the molecules.
