Refractive index of cellulose
WebThe refractive index (RI) of the nanocrystalline cellulose, extracted from wood by sulfuric hydrolysis, was approximately 1.5. The RI was determined using the Becke line microscopy method. This method consists of two conditions: particle is larger than 50 µm and the particles are dispersed in liquid in which they do not dissolve.
