N2 - Extensive progress has been made on the application of organic semiconductors (OSCs) in organic field-effect transistors (OFETs); however, low reproducibility and poor stability of OSCs have limited their industrial applications. One potential strategy to overcome these limitations is to blend OSCs with insulating commodity polymers. The resultant bicomponent blends can be used to fabricate OFETs with low cost, high performance, and long-time retention. In addition, insulator blending is also identified as a facile and effective approach to enhance the OSC properties, with some unexpected features even superior to neat OSCs. Herein, the present advances of OSCs/insulator blends in the OFET configuration are reviewed. The perspectives on the intrinsic properties of insulator blends, including morphology and trap elimination, are presented for the purpose of strategic device optimization. Accordingly, the effect of different insulator components on device performance is also discussed.
