摘要
用静电纺丝法制备电子聚合物聚对苯乙炔(PPV)与非共轭聚合物聚乙烯醇(PVA)的复合纳米纤维。对复合纳米纤维的发光性质和形态进行了表征。与PPV薄膜相比,复合纳米纤维的发射光谱在PPV含量较高时(如1∶1(质量比)时)变化不明显;而含量较低时(如1∶4(质量比)时)有明显的蓝移现象;当PPV的含量非常低时(如1∶99(质量比)时),光谱的蓝移值趋于确定。
The PPV/PVA blend nanofibers were fabricated by electrospinning. The luminescence and form of blend nanofibers were characterized. It was found that when the ratio of PPV and PVA is 1 : 1(w/w), the emitting spectrum is not obvious change to pure PPV film's;but when the ratio is lower,such as 1 : 4(w/w),the emitting spectrum of blend nanofibers are obvious blue-shift;when the ratio is sufficient low, such as under 1 : 24
