TEMPO ((2,2,6,6-Tetramethylpiperidin-1-yl)oxy) oxidation is a highly selective method to oxidize primary alcohols of cellulose fibrils without significantly disrupting their crystalline structure. TEMPO oxidized cellulose nanofibrils can be used to prepare highly translucent films for various applications. TEMPO oxidized films can be used, for example, as membranes for heavy metal ion recovery. Oxidized nanofibrils can also be used to produce hydro- and aerogel structures. Such materials have potential as absorbent materials or as materials in medicine. TEMPO oxidation reactions and stability of different kinds of cellulose surfaces can be observed using quartz crystal microbalance with dissipation monitoring (QCM-D). Optimal oxidation conditions depend greatly on the cellulosic material used for surfaces. TEMPO oxidized nanocellulose surface for QCM-D can also be produced by more conventional method, spin coating.
