摘　　要：为实现水污染体系中油水的高效分离,采用溶液聚合法合成丙烯酸丁酯-甲基丙烯酸羟乙酯共聚物、甲基丙烯酸丁酯-甲基丙烯酸羟乙酯共聚物,以共混溶液为纺丝液,采用静电纺丝技术制备得到可用于分离不同油水混合物的微结构可调的纤维膜材料,并研究其对不同油水混合物的分离能力。结果表明:2种共聚物溶液以体积比为3∶7共混后制得的纤维膜对柴油/水、葵花籽油/水混合物的分离效果显著;针对上述2种油水混合物,重复使用共混纤维膜5和7次时,共混纤维膜对2种油水混合物的分离时间分别低于390、110 s;将四氢呋喃引入上述共混溶液继续调节静电纺纤维膜的微结构,所得纤维膜可快速将高黏度乳化油从水中分离出来。In order to realize the efficient separation of oil and water in water pollution system,poly(butyl acrylate-co-hydroxyethyl methacrylate)and poly(butyl methacrylate-co-hydroxyethyl methacrylate)were synthesized by solution polymerization.The blended solution with the two polymers was used for electrospinning to prepare micro-structurally adjustable fibrous membrane material to separate different oil/water mixtures,and its separation capacity for different oil/water mixtures was explored.The results demonstrate that the fibrous membrane obtained from blending the two copolymer solutions in the volume ratio of 3∶7 shows significant separation capability for diesel/water mixture and sunflower oil/water mixture.When it is repeatedly used for 5 times and 7 times to separate the two oil/water mixtures,the separation time are lower than 390 s and 110 s,respectively.Tetrahydrofuran(THF)was introduced into the above-mentioned blended solution to adjust continually the microstructure of the electrospun fibrous membrane,and the obtained fibrous membrane is proven to separate highly viscous emulsified oil from water quickly.
