Nano-Technology Of Cellulose Materials

Michael Ioelovich, Alex Leykin

Nano-technology comprising steps of the acid depolymerization of natural cellulose materials and the mechanical disintegration of non-dried samples have been developed for obtaining nano-scale particles. Low-stress mechanical treatment of the hydrolyzed cellulose doesn’t permit separation of nano-particles. In order to obtain nano-cellulose having Cl crystalline structure the specified acid concentrations together with the high-stress mechanical disintegration should be used. The correlation between particle size and concentration of the acidic catalyst was established. Structural transformations of cellulose fibers at the hydrolysis and mechanical disintegration are discussed.
