Abstract

In this work, we obtained dispersions of nanosized cellulose particles and measured the zeta potential of particles at pH from 1 to 14. It was found that CNF retains sedimentation stability at pH from 3 to 11. At the same time, CNF obtained by acid treatment with homogenization has the maximum zeta potential about -62 mV at pH = 6. CNF obtained by oxidative treatment with homogenization has a maximum zeta potential of about -46 mV at pH = 7. CNC obtained by oxidative treatment with homogenization retains sedimentation stability at pH from 4 to 11 and has a maximum zeta potential of about -73 mV at pH =4.
