摘要
Abstract
Using the dissolution regeneration method,cellulose hydrogel was prepared.Under alkaline as a catalyst,the hydrolysis-conden-sation rate of tetraethyl orthosilicate(TEOS)was controlled to regulate the size of the prepared SiO2 particles,followed by the composite of cellulose and SiO2,which was then freeze-dried to obtain a SiO2/cellulose composite aerogel.After hydrophobic modification with alkyl silox-ane,a superhydrophobic oleophilic SiO2/cellulose composite aerogel was prepared.The results indicated successful SiO2 incorporation into the cellulose aerogel,and the prepared SiO2/cellulose composite aerogel had a porous structure.At a pH value of 10,SiO2 sphere had a size range of 50～200 nm,and SiO2/cellulose composite aerogel had a static contact angle of 158.9° and a roll-off angle of 3.2°,of which oil ab-sorption capacity was 12.8 times its own weight.关键词
