Coatings

Cellulose nanoparticles have a reactive surface that facilitates grafting chemical species to achieve different surface properties (surface functionalization). This offers unique opportunities to alter the effective properties of these particles so that they may be useful in new applications. With this in mind, one area of surface functionalization is in coatings, in which nanosized particles of metal or ceramic are precipitated on the particle surface. Depending on the coating structure it will alter the effective properties of the cellulose nanoparticle-coating assembly.

Our approach uses a standard room temperature precipitation reaction to coat CNCs with silver nanoparticles. To characterize the precipitate formation we use the following: Transmission electron microscopy (TEM), election energy loss (EELS) spectrum, and UV-vis spectrum.
