摘要：

Plasma-induced graft polymerization (PIGP) is an efficient method for constructing functionalized pore-filling type materials. This study imparts new information about the significance of substrate infiltration process and pH of the monomer solution that determines the degree of grafting via PIGP inside pores. Herein, we report that high-density grafting of 2-acrylamido-2-methylpropane sulfonic acid on porous polyethylene membrane can be achieved by incorporating an infiltration agent under acidic condition. In addition, this technique is unique in its initiation step: it proceeds even after most radicals has disappeared prior to polymerization at temperature ranging from 25 to 40 degrees C, which is much lower than conventionally used 80 degrees C. It offers a very facile PIGP method for thermally labile monomers.
