Nanocomposites of TiO
2
and multi-walled carbon nanotubes (MWNTs) were produced by the addition of different concentrations of MWNTs to a TiO
2
sol matrix. Conductive coatings were prepared by spin coating the nanocomposite sols on glass substrates and sintering the samples at 300 ° C for 15 min. No crystalline phase of TiO
2
was formed at this temperature. The sheet resistance of the coatings was decreased from some hundreds of M Ω/sq to just a few k Ω/sq by the addition of MWNTs to the TiO
2
matrix. Moreover, sintering of the coatings in a reducing atmosphere has lead to a lower sheet resistance than that presented by coatings sintered in air. The lowest resistivity of 2.0 x 10
-1
Ω.cm was obtained by coatings prepared with 5.0 mg/ml MWNTs in the composite sol. The optical, structural and electrical properties of the coatings were correlated and demonstrated.
