Electrochemical Properties and Structure of Membranes from Perfluorinated Copolymers Modified with Nanodiamonds.

In this study, we aimed to design and research proton-conducting membranes based on Aquivion-type material that had been modified with detonation nanodiamonds (particle size 4-5 nm, 0.25-5.0 wt.

Improving PFSA Membranes Using Sulfonated Nanodiamonds.

Aquivion-type perfluorosulfonic acid membranes with a polytetrafluoroethylene backbone and short side chains with sulfonic acid groups at the ends have great prospects for operating in hydrogen fuel cells. To improve the conducting properties of membranes, various types of nanofillers can be used. We prepared compositional Aquivion-type membranes with embedded detonation nanodiamond particles.
