This paper presents the preparation of superhydrophobic magnetic cellulose-based particles by using the cellulose as the raw material. The bamboo pulp is dissolved by the NaOH/urea aqueous solution, and the cellulose particles are regenerated in the water. The superhydrophobic magnetic cellulose particles are obtained by modifying the magnetic cellulose particles with the noctadecyltrimethoxysilane(ODTMS). The morphology, the chemical structure and the thermal stability of the modified cellulose particles are analyzed by the scanning electron microscopy(SEM), the Fourier transform infrared spectroscopy(FT-IR) and the thermogravimetry(TG), respectively. The modified-cellulose particles are superhydrophobic and magnetically responsive. Its water contact angle is 151.2°. The modified-cellulose particles can encapsulate the water and the glycerol droplets to form stable liquid marbles.
