Abstract
The invention relates to novel block copolymers that enable a good dispersion of nanofillers in water and also to a dispersion of nanofillers obtained owing to these block copolymers. This dispersion may be used as a transparent electrode in organic solar cells or other photoemitter or photoreceptor devices.
