The present invention relates to a process for preparing transparent conductive oxides, comprising the following steps in the sequence of a-b-c: (a) reaction of at least one starting compound (A) comprising at least one metal or semimetal M and optionally of a dopant (D) comprising at least one doping element M′, where at least one M′ is different than M, in the presence of a block copolymer (B) and of a solvent (C) to form a composite material (K), (b) optional application of the composite material (K) to a substrate (S) and (c) heating of the composite material (K) to a temperature of at least 350° C., wherein the block copolymer (B) comprises at least one alkylene oxide block (AO) and at least one isobutylene block (IB). The present invention further relates to the transparent conductive oxides thus obtainable, and to their use in electronic components, as an electrode material and as a material for antistatic applications. The present invention finally relates to electronic components comprising the transparent conductive oxides.
