摘要：

Applications of cellulose nanofibril are highly dependent on its dimension (length and width). Quick and easy methods for measuring cellulose nanofibril dimensions are critical in process quality control. A nanoparticle size analyzer (Dynamic laser scattering) was applied for cellulose nanofibril characterization and two distinct peak areas were observed as one was its width (2-50 nm) and another was its length (100-500 nm). The width and length of the nanofibril from the nanoparticle analyzer were lower than those of TEM image analysis but each samples showed a similar trend between nanoparticle analyzer and TEM image analysis. Thus, the dynamic laser scattering nanoparticle analysis is recommended as a quality control tool for cellulose nanofibril making process for estimation of its length and width. © 2019 Korean Technical Assoc. of the Pulp and Paper Industry.
