摘要

通过种子溶胀乳液聚合诱导相分离法合成具有严格分区的雪人状Janus颗粒，分别对两侧分区结构连续改性，制备得到具有磁响应性的两亲雪人状Janus颗粒.该颗粒一侧带有亲水性咪唑基团（—Im），另一侧带有疏水性烷基长链（—C18），对油相具有强的负载能力；同时该颗粒具有顺磁响应性，其可以稳定在油水界面上，并在磁场作用下驱使乳液液滴进行运动，实现高效的油水分离应用，颗粒可回收循环利用，符合绿色化学要求.该功能性Janus颗粒的制备方法具有普适性，对颗粒两侧进行不同改性，可以获得一系列不同组成和功能的Janus颗粒，为制备先进功能高分子材料提供新的思路.

两亲性雪人状Janus颗粒磁性油水分离功能高分子

Abstract:

The snowman-like Janus particles with strict partition were synthesized by seed swelling emulsion polymerization induced phase separation.The two side partition structures were continuously modified,and the amphiphilic snowman-like Janus particles with magnetic were prepared.One side of the particle has hydrophilic imidazole group(—Im),and the other side of the particle has a long chain of hydrophobic alkyl(—C18),which has a strong loading capacity of the oil phase for separation of oil and water.Meanwhile,the particles have paramagnetic responsiveness.The particles can stabilize at the oil-water interface and control the move of emulsified droplets under magnetic field for separation of oil and water.The particles can be recycled which is conform to the requirements of green chemistry.The method for preparing functional Janus particles is universal,and a series of Janus particles with different compositions and functions can be obtained through different modifications on both sides,which provides a new idea for the preparation of advanced functional polymer materials.
