Telecommunications, Xi’an 710121, China 10.3762/bjnano.11.53 Abstract Among the patterning technologies for organic thin-film transistors (OTFTs), the fabrication of OTFTelectrodes using polymer templates has attracted much attention. However, deviations in the electrode alignment occur because the coefficient of

Organic thin-film transistors (OTFTs) provide a platform to construct next
aligned [7]. However, the polymer template has a high coefficient of thermal expansion (CTE), resulting in alignment deviations of the OTFTelectrodes [8][9].
Currently, one of the measures to reduce the CTE of polymer templates is wet blending, in which the low-CTE nanomaterial is directly incorporated
