In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Effect of cross-linker length on performance of multication cross-linked poly(p-terphenyl isatin) anion exchange membranes for fuel cells, published in 2021-12-27, which mentions a compound: 111-18-2, mainly applied to crosslinker length fuel cell anion exchange membrane, COA of Formula: C10H24N2.
As a key component of anion exchange membrane fuel cells (AEMFCs), anion exchange membranes (AEMs) have been investigated in the last decades. Herein, a series of multication cross-linkers were introduced into side-chain-type poly(p-terphenyl isatin) to develop high-performance and long-term stable AEMs. Addnl., the effects of the hydrophilic cross-linker length on the membrane performance were systematically investigated. The resulting cross-linked membranes possess a low swelling ratio (<18% at 80 °C) and high tensile strength (51.1-58.3 MPa). Notably, the cross-linker length influences the AEM internal morphol. With hexyl as the spacer between backbones and cation groups in the cross-linker, 0.9q-PTI-6C exhibits the highest hydroxide ion conductivity of 118.5 mS/cm at 80 °C, which is ascribed to well-developed ion channels. Furthermore, alkyl spacer chains and cross-linked networks contribute to the excellent alkali stability of membranes. After immersion in 2 M NaOH for 1200 h at 80 °C, 0.9q-PTI-8C only shows 11 and 12.7% losses in ion conductivity and ion exchange capacity (IEC), resp. The fuel cell fabricated using 0.9q-PTI-6C can achieve the maximum power d. of 310 mW/cm2 at 80 °C. Compounds in my other articles are similar to this one(N1,N1,N6,N6-Tetramethylhexane-1,6-diamine)COA of Formula: C10H24N2, you can compare them to see their pros and cons in some ways,such as convenient, effective and so on.
