Abstract:In this study， sugarcane cellulose aerogel with anisotropy was prepared by top-down method using sugarcane as raw material. The lignin and hemicellulose in sugarcane cell wall were removed in-situ using NaOH and H2O2， and then TEMPO oxidation method was used to separate the originally gathered cellulose， and sugarcane cellulose aerogel was obtained after freeze-drying. The samples were characterized by universal material testing machine， specific surface area and aperture analyzer， and thermogravimetric analyzer. The results showed that the maximum stress sugarcane cellulose aerogel was up to 0.28 MPa and it’s specific surface area was up to 22.4 m2/g which showed excellent thermal stability. After hydrophobic modification with methyltrimethoxysilane （MTMS）， the sugarcane cellulose aerogel was transformed into a superhydrophobic cellulose aerogel with water contact angle up to 147.17° and the maximum oil adsorption up to 15.86 g/g.
