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

ABSTRACT: 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. %). These nanodiamonds carried different functional groups (H, OH, COOH, F) that provided the hydrophilicity of the diamond surface with positive or negative potential, or that strengthened the hydrophobicity of the diamonds. These variations in diamond properties allowed us to find ways to improve the composite structure so as to achieve better ion conductivity. For this purpose, we prepared three series of membrane films by first casting solutions of perfluorinated Aquivion^®-type copolymers with short side chains mixed with diamonds dispersed on solid substrates. Then, we r
