The invention discloses a preparation method of super-hydrophobic magnetic nano-crystalline
cellulose paper, relates to a preparation method of magnetic nano-crystalline
cellulose paper, and aims to solve the technical problems of poor
hydrophobic effect and no
magnetism of nano paper prepared by an existing method. The method comprises the following steps: 1, preparation of nano-crystalline
cellulose water liquid; 2, preparation of nano-crystalline cellulose-magnetic
nanoparticle mixed liquor; 3, preparation of a hydrophobic substance; 4, suction
filtration film-forming of magnetic nano-crystalline cellulose; 5, preparation of the super-hydrophobic magnetic nano-crystalline cellulose paper. The super-hydrophobic magnetic nano-crystalline cellulose paper prepared by the method has the characteristics that the hydrophobic
contact angle can reach up to 150 degrees or more, the
rolling angle is less than 10 degrees, the
magnetic intensity can reach 60emu / g, the stretching stress can reach 90MPa, and the maximal
pyrolysis temperature can reach 360 DEG C. The preparation method belongs to the field of nano-crystalline cellulose paper preparation.
