单宁酸-纳米协同改性胶原纤维多孔材料的制备及其油水分离性能
Preparation and oil-water separation property of tannic acid-nanoclay synergistically modified collagen fiber-based porous materials
摘要
Abstract
In recent years,owing to their advantages of being renewable and abundant,retaining unique multi-scale pore structure,and exhibiting excellent separation ability,reusability and biodegradability,biomass-based porous materials represented by collagen fibers have attracted much attention in the fields of oil-containing wastewater treatment.To address the problems of low oil-water separation efficiency of collagen fiber porous materials,a novel collagen fiber-based porous material with oil-water separation performance was prepared by modification of collagen fibers using a synergistic cross-linking system of tannic acid and metal ion(aluminum and zirconium)doped Laponite nanoplatelets.The results showed that the synergistic cross-linking system improved the self-standing,formability and porosity of the porous material without altering the triple-helix conformation of the collagen and stabilizing the collagen microstructures.Moreover,after the synergistic cross-linking modification,the shrinkage temperature,water contact angle and oil-water separation efficiency of the collagen fiber porous material network were increased to over 90℃,98° and 68%,respectively,indicating that the thermal stability,hydrophobicity and oil-water separation properties were improved.关键词
