{"product_id":"caefcaeidna5","title":"Anion Exchange Ionomer Dispersion (NEXIONIC NA5) for Alkaline Electrolyzer and Fuel Cell, 10 mL\/bottle, CAEFCAEIDNA5","description":"\u003cp\u003eNEXIONIC was developed to provide a high-performance, stable alternative for alkaline electrochemical systems, bridging the gap between established brands like Fumatech (FAA-3) and specialized materials like PiperION or Sustainion.\u003c\/p\u003e\n\u003cp\u003eThe NEXIONIC™ NA5 dispersion (often specifically referred to as NA5-05) is a high-stability Anion Exchange Ionomer (AEI) produced by Ion Power. It is based on a Quaternary Ammonium Poly(phenylene terphenyl) (QAPPT) backbone. In the AEM (Anion Exchange Membrane) research community, NA5 is a premium alternative to older materials like FAA-3, offering a balance between ease of use and extreme chemical durability.\u003c\/p\u003e\n\u003cp\u003eThe performance of NA5 is defined by its ether-bond-free structure. Most traditional anion-exchange materials degrade because their oxygen-based ether linkages are attacked by hydroxide ions (OH-). (1)\u003cstrong\u003e Backbone\u003c\/strong\u003e: A rigid, all-carbon aryl-phenylene chain that is chemically inert in high-pH environments. (2) \u003cstrong\u003eFunctional Group\u003c\/strong\u003e: A quaternary ammonium cation tethered to the rings. These sites facilitate the transport of anions like OH-, Cl-, or HCO3^-.
