Abstract	A novel pendant-type cross-linked anion exchange membrane (pc-AEM) was successfully synthesized using a pre-synthesis approach to precisely control the IEC value and the degree of cross-linking. The physical properties of the pc-AEMs and the non-cross-linked pc-AEMs as well as Nafion 117 were determined, and the results were systematically compared. It was found that the synthesized pc-AEMs show much better dimensional retention capacity than the non-cross-linked pc-AEM and Nafion 117. In addition, the mechanical strength of the pc-AEMs was also remarkably enhanced. By increasing the IEC value of the pc-AEMs to the same level of Nafion 117, the highest ionic conductivity of 0.036 S/cm at 80 °C was reached. The remarkable enhancement of conductivity is chiefly attributed to the construction of highly efficient ionic transport channels resulting from the combined pendant-type and cross-linked architectures of the pc-AEMs.
