| 内容記述 | The hierarchical structures of poly(styrenesulfonic acid)-grafted poly(ethylene-co-tetrafluoroethylene) polymer electrolyte membrane (ETFE-PEM) with different scale ranges including lamellar spacing, interfacial thickness, and intra-structure of conducting layers consisting of graft-polymers and water were evaluated by SAXS in terms of background scattering (IB(q)). First, IB(q) was roughly estimated by modifying Ruland’s method and then optimized to avoid overestimation using a “contribution factor”, which is defined as the contribution of IB(q) to the observed scattering intensities over the entire q range. Then, IB(q) was optimized again by using Ruland’s equation to select proper q-range for interfacial thickness evaluation. The lamellar spacing, which is observed in the low-q range, was not altered by background correction. In contrast, in the high-q range, the interfacial thickness and the internal structures of the conducting layers can be estimated only after correction for the background scattering data. These results clearly show that the hierarchical structures of graft-type PEMs were strongly affected by the background correction in the high-q range. Moreover, the proposed procedure for IB(q) is crucial for the determination of accurate interfacial thickness but not intrastructure of conducting layers. Note that the modified Ruland’s method can be used as an altermative method for determination of background intensity. | |||||
