Abstract:The cellulose nanocrystal （CNC） with good redispersion properties were prepared and utilized as the main raw materials， blended with a certain mass of montmorillonite （MMT） and water followed by hot-pressed to prepare the nanocellulose-based bulk materials with high mechanical strength. The tests of transmissionelectron microscope （TEM），scanning electron microscope （SEM）， atomic force microscope （AFM） and Tyndall effect have proved the prepared CNC with the excellent re-dispersibility. Montmorillonite （MMT）， as a reinforcing agent，was added with CNC powder in different proportions to prepare CNC-MMT composite block materials. Bending resistance test， SEM， contact angle test， water absorption test and thermogravimetric （TG） analysis were used to investigate the bending performance， surface morphology， hydrophilicity and thermal stability of composite materials separately. The results showed that when the content of montmorillonite reached 30%， the bending strength of CNC-MMT was up to 74 MPa， which was higher than that of ordinary commercial plastics.Moreover， CNC-MMT had lower hydrophilic properties and better thermal stability.
