Embodiment 1
[0025] Weigh 0.5 g of cellulose nanocrystal (CNC) solution and 0.5 g of cellulose nanofibril (CNF) solution in a dry mass, place them in a beaker, and ultrasonicate for 1 hour to disperse the CNC / CNF mixed solution. homogeneously, to obtain a mixed solution of all nanocellulose. After the filter membrane is placed in the sand core funnel, the uniformly mixed whole nanocellulose solution is poured into the sand core funnel, and suction filtered for 1.5 hours to a relatively dry state. Then the cellulose and filter membrane obtained by suction filtration were placed on a polytetrafluoroethylene plate, and placed in an oven, and dried at 35° C. for 3 hours. Finally, the water-based mixed filter membrane with a thickness of 0.45 μm and a diameter of 47 mm was peeled off to obtain a highly transparent and high-barrier cellulose paper.
Embodiment 2
[0027] Weigh the cellulose nanocrystal (CNC) solution with a dry weight of 0.1 g and the cellulose nanofibril (CNF) solution with a dry weight of 0.9 g, place them in a beaker, and ultrasonicate for 2 hours to disperse the CNC / CNF mixed solution homogeneously, to obtain a mixed solution of all nanocellulose. After the filter membrane is placed in the sand core funnel, the uniformly mixed whole nanocellulose solution is poured into the sand core funnel, and suction filtered for 6 hours to a relatively dry state. Then the cellulose paper and filter membrane obtained by suction filtration were placed on a polytetrafluoroethylene plate and placed in an oven for drying treatment at 50° C. for 1 h. Finally, the water-based mixed filter membrane with a thickness of 0.45 μm and a diameter of 47 mm was peeled off to obtain a highly transparent and high-barrier cellulose paper.
Embodiment 3
[0029] Weigh the cellulose nanocrystal (CNC) solution with a dry mass of 0.9 g and the cellulose nanofibril (CNF) solution with a dry mass of 0.1 g, place them in a beaker, and ultrasonicate for 0.5 h to make the CNC / CNF mixed solution Disperse evenly to obtain a mixed solution of all nanocellulose. After the filter membrane is placed in the sand core funnel, the uniformly mixed whole nanocellulose solution is poured into the sand core funnel, and suction filtered for 6 hours to a relatively dry state. Then the cellulose paper and filter membrane obtained by suction filtration were placed on a polytetrafluoroethylene plate, and placed in an oven for drying treatment at 15° C. for 8 hours. Finally, the water-based mixed filter membrane with a thickness of 0.45 μm and a diameter of 47 mm was peeled off to obtain a highly transparent and high-barrier cellulose paper.
