Hollowing of inorganic nano/micromaterials can be realized by well‐known Ostwald ripening and Kirkendall processes. However, hollowing of organic polymer without sacrificial templates is seldom seen. Herein, we demonstrate for the first time that conducting polymer nanofibers can be transformed into nanotubes by a simple, effective, and controllable swelling–evaporation strategy. By controlling swelling degree, surface‐patterned poly( o ‐toluidine) (POT) nanofibers, and nanotubes with controllable inner diameter can be fabricated. Novel characteristics of such nanotubes, such as patterned surfaces and sealed tips, will endow them with enhanced properties when applied in fields as controlled drug delivery, noble metal nanocatalysts supporter, and adsorbent for heavy‐metal ions.
