Project Title Photoresponsive Cellulosic Hydrogels
Project Category Innovation
Abstract Stimuli responsive hydrogels are prepared from inexpensive, locally available renewable resources, coupled with highly specific and strong reversible binding motifs. Herein, ultra-high water content cellulosic hydrogels were reported as an aqueous photorheological fluid (PRF), whose rheological properties can be easily modulated via light irradiation. This cellulose-based PRF can undergo a UV-triggered rapid transition from a highly viscous and rigid gel into a Newtonian-like fluid, with a decrease in zero-shear viscosity of over two orders of magnitude. Moreover, the rate of viscosity reduction of these PRFs can be tuned based on the mixture composition and duration of photoirradiation.
