New Ultra-high Pressure Homogenizer Produces Nano-sized Cellulose Fibers

A new Nano DeBee ultra-high pressure homogenizer has been installed in Dr. Yulin Deng’s IPST lab to produce nano-sized cellulose fibers. The instrument is capable of fibrillating regular, micro-sized cellulose fibers to nano-sized fibers. The device forces the cellulose solution through a small-diameter nozzle at upstream pressures of up to 30,000 psi. Due to the high pressure and the small nozzle diameter, the shear rates on the cellulose solution are extremely high. These conditions result in a high degree of fibrillation to the cellulose material, reducing it to nano-sized cellulose fibers. The nanofiber will be used for various research projects at IPST.
