Nanoporosity is an advantageous property for the polymeric membrane films in fuel cells, filters, and drug delivery systems, in which interconnected pores within the material facilitate transport of small molecules across the membrane. Here, we examined the effect of a DC electric field on the pore structure and oxygen transport of films formed by bicontinuous microemulsion polymerization (BµEP) of 2-hydroxyethyl methacrylate and methyl methacrylate in water containing a cationic surfactant, and compared with those of samples polymerized without an applied electric field. Membranes polymerized through BµEP under an applied electric field that showed 50-130% increase in oxygen transmissibility demonstrated more elongated pore channels in 3D nanoscopic image as well as smaller standard deviations in pore size distribution than those of membranes that exhibited a decrease in oxygen transmissibility. The results suggest the potential of this preparative technique for controlling pore connectivity in a nanostructured membrane system.
