  Structure and Properties of Polymer Electrolyte Membranes Containing Phosphonic Acids for Anhydrous Fuel Cells

  摘要：

  Recently, water-free, proton-conducting polymer electrolytes have been attracting attention because of their possible application as fuel cell membranes at intermediate temperatures (100 to 200 degrees C). Phosphonic acid groups are considered feasible anhydrous proton conducting moieties due to the high degree of proton self-dissociation arising from their intrinsic amphoteric character and high mobility of protonic charge carriers. In this work, we have synthesized and characterized model, phosphonic acidfunctionalized proton-conducting polymers, poly(vinylbenzyloxy-alkyl-phosphonic acid)s, for the purpose of exploring the relationship between molecular design, nanostructure, and performance characteristics. These novel proton conducting materials were characterized for their thermal stability, nanostructure, and performance properties. Thermogravimetric analysis (TGA) indicates that the polymers are thermally stable up to 140 degrees C, where the condensation of phosphonic acid groups starts to occur. Results from small-angle X-ray scattering (SAXS) show a peak corresponding to a Bragg spacing of approximately 21-24 angstrom, which is attributed to layerlike structure formation of the phosphonic acid containing conducting channels. The proton conductivity increases with temperature, reaching a value on the order of 3 X 10(-4) S/cm at 140 degrees C under nominally anhydrous conditions.

  摘要：

  series of α,ω‐heterodifunctional monomers with styrene (St) and maleimide moieties bridged by a varied length of oligo‐ethylene glycol (OEG) linkers were synthesized. Cyclopolymerizations of these monomers through reversible addition–fragmentation chain transfer‐mediated alternating radical copolymerization between intramolecular St and maleimide moieties were investigated. For the monomers with three

  Dynamic covalent networks offer the favorable features of cross-linked polymers as well as the functions of reprocessing, recycling, self-healing, reshaping, and welding; however, it is a challenge to design readily monomer-recovery, highly malleable, catalyst-free, dynamic materials. Here we report the first design of acetal dynamic networks to address this challenge. Acetal dynamic networks were

  动态共价网络提供了交联聚合物的有利功能，以及后处理，回收，自修复，整形和焊接的功能。但是，设计易于回收的单体，高延展性，无催化剂的动态材料是一个挑战。在这里，我们报告乙缩醛动态网络的第一个设计，以解决这一挑战。乙缩醛动态网络是通过无催化剂“点击”添加多元醇和市售二乙烯基醚，而不会释放小分子。小分子模型化合物在没有催化剂的情况下表现出热诱导的缩醛交换。动态交换乙缩醛有两种机制：一种是乙缩醛的复分解，另一种是反乙缩醛化。乙缩醛动态共价网络表现出出色的延展性和可回收性。他们提出了在高温下应力的快速松弛。在150°C下，可以在10分钟内完成热压恢复。同时，在100°C的热水处理下，在1小时内以92％的回收率回收了起始原料，并且可以将其与市售的二乙烯基醚重新交联以获得缩醛网络。两种方法回收的乙缩醛网络均保持了原有的结构和性能。
