Hybrid systems based on nanodiamond and cesium dihydrogen phosphate

The first data were obtained on the study of a composite systems based on (1-x)CsH₂PO₄-x nanodiamonds (ND). It is shown that a matrix of nanodiamonds is suitable for the creation of composites based on CsH₂PO₄. The phase composition of composite was investigated; the CsH₂PO₄ structure remains at x = 0-0.5. The particle size of CsH₂PO₄ and degree of crystallinity change markedly even at x = 0.1, which corresponds to a total volume fraction of nanodiamonds, fv = 0.62%. Due to the interface interaction, salt dispersion, the formation of defects and partial salt amorphization proton conductivity at low temperatures increases with increasing molar fraction of nanodiamonds more than one order of magnitude at x = 0.5; superionic one is close to pure CsH₂PO₄.
