WANG Xiao-hong, QIU Long-zhen. Organic Thin Film Transistors Based on Blends of Poly(3-hexylthiophene) and Polycaprolactone[J]. Chinese Journal of Luminescence, 2012,33(8): 857-862 DOI: 10.3788/fgxb20123308.0857.
A blending crystalline system containing poly(3-hexylthiophene) and polycaprolactone was investigated. The electric measurements reveal that the field-effect performances of blend films
such as mobility
on/off current ratio and threshold voltage
decrease slowly with P3HT content reducing. However
the devices still have relatively good performance even P3HT content was 40%. According to the AFM studies
vertical phase separation occurs in the blend films
and a connective semiconducting layer can be observed in the interface between insulating layer and active layer
which is beneficial to transport of charge carriers.
