Abstract

A series of novel trisulfonated phosphine oxide polymers (tsPEPO-x) with different sulfonation degrees were prepared by intermolecular polymerization of trisulfonated phosphine monomer and 4,4′-dihydroxydiphenyl ether. The properties of these membranes were investigated in detail. The results showed that these membranes, especially those with high sulfonation degree, exhibited excellent overall performance. For example, the conductivity of tsPEPO-120 membrane reaches 0.093 S cm−1 at 80°C, which is higher than that (0.087 S cm−1) of Nafion 117. At the same time, the swelling rate is almost equivalent to that (20%) of Nafion 117. Moreover, the membrane also has good oxidation resistance in Fenton’s reagent. The obtained polymers showed good properties. The trisulfonated moieties and diphenyl ether simultaneously played important roles in improving the properties of the polymer.

一种新型质子交换膜，由含有二苯基醚部分的三磺化聚(芳烯醚氧化膦)衍生而成

以三磺化膦单体与4,4′-二羟基二苯基醚为原料，通过分子间聚合制备了一系列磺化程度不同的新型三磺化氧化膦聚合物(tsPEPO-x)。对这些膜的性能进行了详细的研究。结果表明，这些膜，特别是磺化程度高的膜，具有优异的综合性能。例如，在80℃时，tsPEPO-120膜的电导率达到0.093 S cm−1，高于Nafion 117的0.087 S cm−1。同时，溶胀率与Nafion 117的溶胀率(20%)相当。此外，该膜在Fenton试剂中也具有良好的抗氧化性能。所得聚合物具有良好的性能。三磺化基团和二苯基醚同时对聚合物的性能起着重要的改善作用。

期刊介绍： Health Services Management Research (HSMR) is an authoritative international peer-reviewed journal which publishes theoretically and empirically rigorous research on questions of enduring interest to health-care organizations and systems throughout the world. Examining the real issues confronting health services management, it provides an independent view and cutting edge evidence-based research to guide policy-making and management decision-making. HSMR aims to be a forum serving an international community of academics and researchers on the one hand and healthcare managers, executives, policymakers and clinicians and all health professionals on the other. HSMR wants to make a substantial contribution to both research and managerial practice, with particular emphasis placed on publishing studies which offer actionable findings and on promoting knowledge mobilisation toward theoretical advances. All papers are expected to be of interest and relevance to an international audience. HSMR aims at enhance communication between academics and practitioners concerned with developing, implementing, and analysing health management issues, reforms and innovations primarily in European health systems and in all countries with developed health systems. Papers can report research undertaken in a single country, but they need to locate and explain their findings in an international context, and in international literature.
