Anion exchange membranes (AEMs) with robust alkaline stability and high ionic conductivity are imminently required for the promising electrochemical energy conversion devices – fuel cells.
Introducing dynamic covalent bonding into thermoset polymers has received considerable attention because they can repair or recover when damaged, thereby minimizing waste and extending the service life of thermoset polymers. However, most of the yielded dynamic covalent bonds require an extra catalyst, high temperature and high-pressure conditions to trigger their self-healing properties. Herein, we report on a catalyst-free bis-dynamic covalent polymer network containing vinylogous urethane and
Biobased thermosetting polymers have attracted interest owing to their renewable source materials, long service life, and properties comparable to those of petroleum-based materials. However, the fabrication of those that merge exquisite mechanical properties with fast self-healing performance has not been demonstrated to date. In this work, a biobased polyurethane coating was constructed using curcumin dioxime (CD), castor oil (CO), and isophorone diisocyanate (IPDI) to fulfill these features.
Superionic Disulfonic Acid Polymers In article number 2501998, through controlled polymerizations of precisely engineered disulfonic acid monomers with well-defined functional group arrangements, Moon Jeong Park and co-workers simultaneously enhance the mechanical strength and ion transport properties of acid-functionalized polymers. This precise molecular design enables superionic conduction in elastic states, revealing unexpected hydrophobic behavior, and enabling the decoupling of ion relaxat
Abstract Acid‐functionalized polymers have received significant attention for use in energy conversion systems. Sulfonated aromatic polymers have been widely studied for utilization in energy conversion systems; however, the occurrence of side reactions or uncertainties in the substitution has hindered progress in enhancing their properties. In this study, an approach is presented for developing superionic sulfonated polymers through the strategic design of disulfonic acid polymers with precisel
