摘要

开发绿色高效的油水分离材料对含油废水处理具有重要意义。针对传统油水分离材料耐久性不足、制备过程依赖石油基原料等问题，本文以生物基腰果酚为原料，与己二胺、多聚甲醛通过无溶剂曼尼希反应合成了双官能苯并噁嗪单体Ca-DAH，并采用喷涂和热固化工艺在PET织物表面构筑Ca-DAH/SiO

复合涂层。结果表明，当SiO

与Ca-DAH的质量比为0.6时，改性织物表面形成均匀的微/纳米粗糙结构，水接触角达到155.0±1.5

，表现出良好的超疏水性。该织物可在重力驱动下分离多种重油/水混合物，平均油通量为30285-34252 L·m

，分离效率为90.8%-98.6%。此外，Ca-DAH/SiO

-0.6改性织物还可用于多种轻油的收集，并在酸碱浸泡、盐浸泡、紫外照射和热处理后保持较好的油水分离性能，为绿色耐久型油水分离材料的制备提供了可行思路。

Abstract

Developing green and efficient oil-water separation materials is of great significance for the treatment of oily wastewater. To address the insufficient durability of conventional oil-water separation materials and their dependence on petroleum-based raw materials during preparation

a bifunctional benzoxazine monomer

Ca-DAH

was synthesized from bio-based cardanol

hexamethylenediamine

and paraformaldehyde via a solvent-free Mannich reaction. Subsequently

Ca-DAH/SiO

composite coatings were constructed on PET fabrics through spray coating followed by thermal curing. The results showed that when the mass ratio of SiO

to Ca-DAH w

as 0.6

a uniform micro/nano rough structure was formed on the surface of the modified fabric

and the water contact angle reached 155.0±1.5

indicating good superhydrophobicity. The fabric could separate various heavy oil/water mixtures under gravity

with average oil fluxes of 30285-34252 L·m

and separation efficiencies of 90.8%-98.6%. In addition

the Ca-DAH/SiO

-0.6 modified fabric could also be used to collect various light oils and maintained good oil-water separation performance after acid/alkali immersion

salt soaking

ultraviolet irradiation

and thermal treatment

providing a feasible strategy for the preparation of green and durable oil-water separation materials.
