摘要：

An anion exchange membrane (AEM) was made with a modified polyketone (PK). AEMs of polyamines were prepared in a three-step procedure: (I) PK synthesis using ethylene and carbon monoxide, supported by a Pd catalyst, followed by the introduction of 1,2-diaminopropane to yield the polymeric amines; (II) solvent casting of the modified PK with a low degree of amination; (III) iodomethylation to form the AEM (PK-PDAPm(I)), followed by ion exchange with KOH (PK-PDAPm(OH)). The structure of the modified polyketone was characterized using FT-IR, and UV-vis spectroscopy, demonstrating the successful introduction of amine in the PLC. The conductivity of the AEM was studied using broadband electric spectroscopy (BES) in the temperature range from 100 to 120 degrees C: the highest value of 9 x 10(-4) Scm(-1) was reached at 120 degrees C for the ionic conductivity of PK-PDAPm(l), followed by PK-PDAPm(OH) with values of the same order of magnitude (10-4 Scm(-1)). Thermogravimetry showed that the material is thermally stable up to 200 degrees C. (C) 2016 Elsevier Ltd. All rights reserved.
