The ease in structural modification, redesign and development of multifunctional polymer semiconductors have led to significant advances in organic electronic device applications such as organic light emitting diodes (OLED), organic photovoltaics (OPV), organic thin film transistors (OTFT), and organic sensors. In this article, we reviewed recent techniques and strategies employed toward the optimization of conjugated polymer films for high sensing performance in OTFT-based gas sensors. Significant enhancements, particularly in gas selectivity, sensitivity, detection limit, response/recovery time of OTFT-based gas sensors by polymer film morphology and thickness control, functionalization of conjugated polymers with chemical groups and the use of doped/blended inorganic or dielectric materials and conjugated polymer composites as active layers are discussed here.
Keywords:organic thin film transistors;conjugated polymers;gas sensors;sensing mechanism;morphology influence;film thickness
