Abstract
Proton conductors play a significant role in various fields, and recent research has focused on exploring crystalline porous materials for their favourable proton-transport properties. However, synthesizing these materials often poses challenges, especially in achieving crystallinity. In this study, we have successfully developed an innovative approach by constructing an amorphous microporous polymer (AMP) structure. Unlike traditional methods that require crystallization, our AMP maintains a certain pore space, while avoiding the need for strict crystallinity. Remarkably, this newly developed AMP displays high-density sulphonic acid sites on its skeleton, enabling it to function as an efficient proton conductor across a wide range of relative humidity (RH) levels. At 70°C and 100% RH, it achieves an impressive maximum conductivity value of 3.34 × 10−3 S cm−1. Such an excellent performance can be attributed to the low activation energy for proton conduction, measuring a mere 0.266 eV. This signifies a Grotthuss mechanism, indicating that protons readily jump along hydrogen bonds within the material.
期刊介绍：
Journal of Chemical Sciences is a monthly journal published by the Indian Academy of Sciences. It formed part of the original Proceedings of the Indian Academy of Sciences – Part A, started by the Nobel Laureate Prof C V Raman in 1934, that was split in 1978 into three separate journals. It was renamed as Journal of Chemical Sciences in 2004. The journal publishes original research articles and rapid communications, covering all areas of chemical sciences. A significant feature of the journal is its special issues, brought out from time to time, devoted to conference symposia/proceedings in frontier areas of the subject, held not only in India but also in other countries.
