WebThe usage of anion-exchange membranes could solve this problem. However, the long-term stability of such materials remains unproven. This study compares two pre … WebIon exchange reactions can be used to convert PFSA ionomers from their original acid form to a salt form using various cations without loss of strength or thermal and chemical stability [ 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 ]. These properties allow PFSA salts to be used as polymer electrolytes with unipolar cation conductivity. WebWhen using a membrane patch that has not been equilibrated, like those pro-vided by the membrane plugin of VMD, we strongly recommend to perform ﬁrst a simulation in which everything (water, ions, protein, lipid headgroups) except lipid tails, is ﬁxed. In this way we will induce the appropriate disorder of a ﬂuid-like bilayer. des-1008c datasheet
