제목 Programmed Suspension Rheology of Biocellulose Nanofluids with Controlled Reversible Sol-Gel Transition
초록 In this study, we propose a new approach to program the rheological properties of BCNF-based smart nanofluids. For this, we conducted TEMPO-mediated oxidation in the aqueous solution. Then, we controlled aspect ratio of BCNFs through a mechanical fibrillation process. To give additional interaction-driven chain association, we utilized the host-guest interaction that enables the shear stress-dependent reversible sol-gel transition. The BCNF gel network displays strong viscosity enhancement as well as controlled reversible sol-gel transition in response to the applied shear stress. These results highlighted that our attractive BCNF nanofluid system is expected to enable the development of new intelligent formulations in cosmetics, food and pharmaceutical industries.
