Uniform, separated BaCrO 4 single‐crystalline nanofibers with high aspect ratio (> 5000, see Figure) can be fabricated at room temperature in aqueous solution using a double hydrophilic block copolymer as structure‐directing agent and introducing colloidal nucleation agents. Such fibers represent a model case for advanced polymer fillers and the exploration of quasi‐1D nanostructures with interesting electrical, optical, or catalytic properties.
