One‐dimensional (1‐D) ZnO nanorods with various sizes were synthesized in colloidal systems formed by PEO‐PPO‐PEO block copolymers. The experimental results revealed that the growth of ZnO nanorods was dependent on the molecular structure of polyether. It was known that L64 (EO13PO30EO13) and F68 (EO80PO30EO80) had the same size PPO block but different content of PEO. We concluded that the size of the ZnO products obtained in F68 was larger due to its longer PEO chain.
