纤维素纳米纤维-单宁酸气凝胶的制备及疏水亲油性能
Preparation and hydrophobic lipophilic properties of cellulose nanofiber-tannic acid aerogel
摘要
Abstract
Cellulose aerogel has become a hot topic in the research of oil stain adsorption materials due to its advantages such as low density,large specific surface area and high porosity.Hydrophobic lipophilic aerogels were prepared using tannic acid(TA),cellulose nanofibers(CNF)and methyltrioxysilane(MTMS).The research found that the aerogel prepared with a mass ratio of CNF,TA,and MTMS of 20∶3∶12 had the best performance.After 10 min of contact with water droplets on its surface,the contact angle could reach 106.0°,and the oil droplets(hexadecane)could be completely absorbed within 15 s after contact,showing good hydro-phobic and lipophilic properties.The oil-water separation efficiency could reach 97%.After 10 oil-water sepa-ration tests,its separation efficiency could still be maintained at 95%.In addition,this aerogel has excellent re-silience.When it is squeezed 10 times under both dry and wet conditions,the recovery rate remained above 90%.关键词
