Single walled carbon nanotubes (SWNT) were dissolved in an acetonitrile+tert-butanol mixture using the amphiphilic Ru-bipyridine complex as a surfactant. The assembly of SWNT/Ru-bipyridine complex was adsorbed on the surface of LiFePO4 (olivine), providing a material with roughly monolayer coverage by the Ru-bipyridine complex and ca. 0.04 wt% of SWNT.

Jednostěnné uhlíkové nanotuby (SWNT) byly rozpuštěny ve směsi acetonitril+ t-butanol pomocí amfifilního komplexu Ru-bipyridinu fungujícího jako smáčedlo. Soustava SWNT/Ru-bipyridin byla adsorbována na povrch LiFePO4 (olivinu) což poskytlo materiál s pokrytím přibližně monovrstevným a ca. 0.04 váh. % SWNT.
