with 8 8 kg of deionized water the starting material is considered as a mixture of cellulose nanofibers and large cellulose fibers the resulting suspension was stirred at 148 rpm for 21 h to allow swelling thereafter the suspension was homogenized for 170 min through an inline ultra turrax system megatron mt 3000 kinematica ag switzerland at 15 u2032 000 rpm which was connected to the glass reactor the homogenized suspension was subjected to high shearing stress generated through a high shear homogenizer microfluidizer type m 110y microfluidics corporation usa thereby the suspension was pumped for 10 passes through a sequence of 400 u03bcm and 200 u03bcm interaction chambers and subsequently for 5 passes through a sequence of 200 u03bcm and 75 u03bcm interaction chambers at a flow rate of 9 75 g s water was removed from the cellulose nanofiber suspension obtained according to example 1 through centrifugation at 3 u2032 600 rpm for 20 min and subsequent freeze drying for freeze drying 25 ml of solution were poured in a copper cylinder having a diameter of 40 mm the copper cylinder was then immersed in liquid nitrogen and the frozen sample was dried in a freeze dryer without heating and or cooling.
