Smart Cellulose Nanofluids Produced by Tunable Hydrophobic Association of Polymer-Grafted Cellulose Nanocrystals
Cellulose
fibrils, unique plant-derived semicrystalline nanomaterials with exceptional
mechanical properties, have significant potential for rheology modification
of complex fluids due to their ability to form a physically associated
semiflexible fibrillary network. Here, we report new associative cellulose
nanocrystals (ACNCs) with stress-responsive rheological behaviors
in an aqueous solution. The surface-mediated living radical polymerization
was employed to graft polyÂ(stearyl methacrylate-<i>co</i>-2-methacryloxyethyl phosphorylcholine) brushes onto the nanofibrils,
and then 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)-mediated
oxidation was conducted to produce nanoscale ACNCs in the aqueous
solution. The ACNCs displayed interfibril association driven by the
hydrophobic interaction that resulted in the formation of a nanofibrillar
crystalline gel phase. We observed that the viscosity of the ACNC
fluid showed reversible shear thinning and temperature-induced thickening
in response to applied shear stress and thermal shock. Moreover, thanks
to generation of a mechanically robust nanofibrillar crystalline gel
network, the ACNC suspension showed extraordinary stability to changes
in salinity and pH. These results highlighted that the interfibril
hydrophobic association of ACNCs was vital and played an essential
role in regulation of stimuli-responsive sol–gel transitions
