采用电子活化再生原子转移自由基(AGET-ATRP)乳液聚合的方法合成了含氟两亲性嵌段聚合物乳液.用红外光谱、核磁共振氢谱和氟谱、X射线光电子能谱对其结构进行分析,发现所有单体参与了反应,产物呈现共聚物结构.接触角测量结果显示,含氟两亲性嵌段聚合物处理岩心后,蒸馏水、油田污水、十六烷、原油的接触角分别由0.70°,0.75°,1.60°和36.83°增加到126.10°,110.51°,97.98°和103.51°,表明聚合物可以改变岩心的润湿性,由强液湿转变为气湿.毛细管上升实验结果表明,合成的聚合物可以使气/水体系和油/气体系中的接触角分别由60°和32°增加到118.31°和77.98°.渗吸实验结果表明,含氟两亲性嵌段聚合物处理岩心后,气/水体系和油/气体系中的液体饱和度明显降低,分别由59％和53.9％降低为35.6％和22.6％.
