Interplay between Swelling Kinetics and Nanostructure in Perfluorosulfonic Acid Thin-Films: Role of Hygrothermal Aging

Autor: Douglas I. Kushner, Ahmet Kusoglu, Meron Tesfaye

Publikováno v: ACS Applied Polymer Materials. 1:631-635

Impacts of processing, storage, and operation on thin-film perfluorosulfonic acid (PFSA) ionomer coatings used in electrodes of electrochemical devices remains unestablished. In this work, alteration of structure–function relationship in ionomers i
