Polycaprolactone (PCL) was grafted to TEMPO-oxidized nanocellulose (TONCs) through a classical ring-opening polymerization reaction mediated by the surface TONC hydroxyl and carboxyl groups. The PCL increased the thermal stability and hydrophobicity without compromising the crystallinity. When TONCs and PCL-grafted TONCs (PTONC) were compared with respect to their perfusion within a segmented polyurethane...
The objective of this research is to provide the first account of a simple preparation of surface fluorinated bulk cellulose nanocrystals and a characterization of their physical and chemical properties. The surface fluorinated, or polyfluorinated cellulose nanocrystals were first generated by reacting bulk cellulose with hydrochloric acid in an aqueous medium to yield cellulose nanocrystals that...
