The phase‐separated structure of blends of the ferroelectric polymer P(VDF‐TrFE) and the semiconducting polymer P3HT used in organic non‐volatile memories is revealed with soft X‐ray spectromicroscopy. These thin‐film blends show a columnar morphology, with P3HT‐rich columns enclosed in a continuous, essentially pure P(VDF‐TrFE) phase favorable for data storage operation.
