Polymers containing small noble‐metal particles are of interest for catalysis and in the generation of optically tunable composites. The currently used process results in materials which are often difficult to process. A method is presented here for the direct transfer of small gold particles from an aqueous sol into a non‐aqueous polymer solution (e.g. a block copolymer, see Figure) facilitating the formation of films.
