Cellulose nanocrystals (CNC), obtained by acid hydrolysis of native cellulose microfibrils as colloidal aquous suspensions, are bioresourced nanoparticles that have great mechanical and optical properties well adapted for the conception of new nanomaterials with high performance. In order to eliminate some of their limitations like sensitivity to salt and absence of interactions control, we studied in this work the chemical modification of these CNC by grafting thermoresponsive polymer chains (polyetheramines Jeffamine®) on the their surface. A first grafting strategy used was a TEMPO oxidation followed by peptidic coupling. After the optimization of the grafting reaction, the new systems (CNC-g-Jeffamine) were characterized and new propert...
