中文摘要	a combination of patterning and film alignment techniques helps to build multi-order polymer architecture for application in flexible electronics. a direct-writing method is employed using microcapillary arrays to prepare semiconducting polymer films with both optical and electrical anisotropy. not only aligned poly(3-butylthiophene) (p3bt) nanowires in neat p3bt films, but also aligned p3bt nanowires within a polystyrene (ps) matrix are obtained, which yields an aligned semiconductor/insulator polymer blend with anisotropic charge transport. the field-effect transistor (fet) mobilities/threshold voltages from both vertical and parallel to alignment directions as well as their dependence on blending ratio are studied. the increased mobility of p3bt/ps blends, as compared with neat p3bt, is observed in both vertical and parallel directions. using this alignment method, fet mobility and threshold voltage of the semiconductor/insulator polymer blends are comprehensively tuned, from which a digital inverter with gain up to 80 is realized. therefore, this work not only helps understanding the charge transport mechanism in semiconducting/insulating polymer blends, but also provides an effective approach towards high-performance field-effect transistors with tunable mobility and threshold voltage.
