用静电纺丝法制备了聚[N，N '-双（2-辛基-十二烷基）萘-1，4，5，8-双（二甲酰亚胺）-2，6-二基]-alt-5，5'-（2，2 '-联噻吩））/聚（乙烯基）P（NDI_2 OD-T_2）/PEO的无缺陷双组分纤维，并用选择性溶剂漂洗，得到纯P（NDI_2 OD-T_2），同时保持纤维形态。通过高电场施加在旋转射流上的拉伸强度诱导聚合物链的优先取向。在单纤维晶体管中实现了与基于薄膜的器件获得的最佳电子迁移率类似的电子迁移率，并且结果不受电介质表面处理的影响。
Defect-free bicomponent fibers of polyl[N,N'-bis(2-octyl-dodecyl)naphthalene-1,4,5,8-bis(dicarboximide)-2,6-diyl]-alt-5,5'-(2,2'-bithiophene))/poly- (ethylenemdde) P(NDI2OD-T2)/PEO are fabricated by means of electrospinning and rinsed with a selective solvent to afford pure P(NDI2OD-T2) while maintaining a fibrous morphology. The elongation strength applied on the spun jet by the high electrical field induces a preferential orientation of polymer chains. An electron mobility analogous to the best obtained with a thin film-based device is achieved in single fiber transistors, and the results are unaffected by the dielectric surface treatment.
