An ionomer (/ ˌ aɪ ˈ ɑː n ə m ər /) (iono-+ -mer) is a polymer composed of repeat units of both electrically neutral repeating units and ionized units covalently bonded to the polymer backbone as pendant group moieties.

Ionomers play a key role in ion transport in a PEFC, as the polymer-electrolyte membrane (PEM) that selectively transports protons from anode to cathode, and as the electrolyte film within the catalyst layers (CLs), wherein electrochemical reactions occur.

Ionomers are polymers in which ionized carboxyl groups create ionic crosslinks in the intermolecular structure. The properties are similar to crosslinked thermosets, even though these resins are processed at conventional temperatures as with other thermoplastic resins (for example, Surlyn® resins by the DuPont Company).

The meaning of IONOMER is any of a class of tough synthetic ethylene-based thermoplastic resins consisting of a copolymer containing cross-links formed by ionic bonds.

Our research involves structural characterization and modeling of transport and mechanical properties of ion-conductive polymers and composites to establish their structure-function-durability relationships and develop design guidelines for electrochemical energy applications.

An ionomer, as one might guess from the name, is an ion containing polymer. (An ion, you might recall, is an atom that has an electric charge, either positive [+] or negative [-].) But an ionomer is more than just a polymer with ionic groups.

Sep 13, 2024 · What is an Ionomer? An ionomer is a class of polymers containing a small amount (typically less than 15 mol%) of ionic functional groups (ionic groups) introduced into a hydrophobic polymer backbone. They are composed of an ethylene-unsaturated carboxylic acid copolymer neutralized with metal salts, typically sodium or zinc.

An ionomer, as one might guess from the name, is an ion containing polymer. An ion, you might recall, is an atom or molecule that has an electric charge, either positive [+] or negative [-].) But an ionomer is more than just a polymer with ionic groups.

Dec 27, 2013 · Ionomers are polymers with bonded ionic species that are used under conditions where the salt groups are in a condensed state. This Feature Article discusses the state of our understanding of ionomers and the historical applications of these nanostructured polymers.

An ionomer is a polymer that comprises repeat units of both electrically neutral repeating units and a fraction of ionized units. Two types are discussed in the following sections. 9.13.1. Ionomer—Ethylene Acrylic Acid Copolymer (EAA)
