Heteropolyacids can retain water in a proton exchange membrane to increase conductivity at high temperatures and low humidity; however, their solubility leads leaching, which limits further application. Herein, we used phosphotungstic acid (HPW) polydopamine (PDA) particles prepare water-insoluble PDA/HPW hybrid (PDW) via hydrothermal reaction. The amino groups of PDA PDW chemically bonded HPW acted as an anchor for HPW. the sulfonated poly(ether ether ketone) (SPEEK) composite containing 15wt% (SPEEK/PDW-15) liquid was 0.052 S⸱cm–1 25 ℃, 63% higher than that SPEEK control (0.032 S⸱cm–1). SPEEK/PDW-15 also showed stable during 80 days testing while immersed water.

杂多酸可以将水保留在质子交换膜中，从而提高其在高温和低湿度条件下的质子电导率；然而，它们在水中的高溶解度会导致浸出，从而限制了它们的进一步应用。在此，我们利用磷钨酸（HPW）和聚多巴胺（PDA）颗粒，通过水热反应制备了不溶于水的PDA/HPW混合物（PDW）。PDW中PDA的氨基与HPW化学键合，成为HPW的锚。含有15wt% PDW的磺化聚醚醚酮（SPEEK）复合膜（SPEEK/PDW-15）在液态水中的质子电导率在25 ℃时为0.052 S cm–1。比SPEEK对照膜（0.032 cm–1）高出63%。在浸入水中80天的测试中，SPEEK/PDW-15复合膜也显示出稳定的质子电导率。

Latent thermal energy storage (LTES) is an important technology to mitigate the discrepancy between source and supply, it has great application prospects in many areas, such as solar utilization, geothermal utilization electricity storage. However, LTES systems suffer from low conductivity of most phase-change materials (PCMs), threatening their large-scale commercial applications. To tackle this challenge, heat transfer enhancement for critically been widely investigated worldwide. Convectional techniques, including fins, nanoparticles multiple PCMs, can significantly improve charging discharging rates system. Recently, rotation-based methods have emerged provide new routes systems, achievements obtained by researchers around world. This study conducted a short review mechanisms applications three methods, aiming deep insights into these novel propel future development
