A facile and controllable phase‐separation route using semiconductor/insulating polymer blends for the fabrication of a microporous semiconductor film is proposed. The microporous film‐based gas sensor exhibits excellent selectivity toward ammonia with a detection limit of 0.5 ppm, a high sensitivity of over 800 at 10 ppm NH 3 , and a response/recovery time of only a few seconds.
