结果表明，如果采取适当的阳极氧化条件，可以同时增加ACF的表面含氧官能团数目和比表面积，从而使ACF吸附性能有较大的提高。

We prepared a serious of functional polymers with RAFT method.First we synthesize a tri-block polymer.One end is hydrophobic PMMA and the other end is hydrophilic PtAA,the middle is the functional epoxy group,which can be fluorinate by CF_3COOH.

本文运用RAFT方法合成了一系列不同链长比例的三嵌段共聚物：聚—聚—聚(PMMA-b-PGMA-b-PtBMA)，然后利用GMA中含有的环氧官能团，合成含氟的一段，最后将PtBMA一段酸解为亲水段PtAA，即形成了双亲双憎的嵌段共聚物。

They can not be used for evacuating the oxygenic,poisonous and
