具有耐燃疏水功能超轻气凝胶的制备及其吸油性
Preparation and oil absorption performance of flame-retardant and hydrophobic ultralight aerogels
摘要
Abstract
In order to prepare cellulose aerogel oil absorbents with oil-water separation performance and flame retardancy,cellulose nanofibers were utilized as the aerogel matrix material,onto which flame-retardant montmorillonite and hydrophobic silane coatings were deposited on the fiber surface,resulting in the fabrication of flame-retardant and hydrophobic cellulose aerogels.The apparent density,flame retardancy,hydrophobicity,and oil absorption performance of the obtained aerogels were determined.It is found that the aerogels possessed fibrous structure with apparent densities ran-ging from 8.10 to 9.95 mg/cm3 and water contact angles exceeding 130°,indicating ultralight and hydrophobic characteristics.During combustion,they exhibited flameless combustion behavior and rapidly ceased burning after removal from the flame,demonstrating excellent flame retardancy.Moreover,they exhibited a maximum oil absorption capacity of(64.63+3.29)g/g,reaching saturation oil absorption within 60 seconds,indicating excellent oil absorption performance.This aerogel provides a potential solution for oil spill treatment applications.关键词
