제목 The Study on Polymer Electrolyte Membrane Characteristics of Polyacrylate Bearing Phosphonic Acid Group
초록 A novel series of phosphonated polymers which had phosphonic acid groups via flexible pendant side chains (PAEPA, PABPA, and PAHPA) was synthesized by the radical polymerization of AEPN, ABPN and AHPN, respectively, followed by hydrolysis with trimethylsilyl bromide.. Among the three polymers, the cross-linked poly[6-(acryloyloxy)hexylphosphonic acid] (PAHPA) membrane prepared by the recombination of polymer radicals with benzoyl peroxide as a radical initiator showed excellent proton conductivity comparable to that of the Nafion 117 membrane in the range of 30–80% relative humidity (RH) at 80 C, regardless of the significantly low water uptake behavior. Furthermore, well-defined phase separation between the hydrophobic and hydrophilic domains was clearly observed by scanning transmission electron microscopy (STEM) and synchrotron X-ray scattering measurements.
