肝素是一种有效的抗凝剂，首次用于合成 PPy 纳米线，不仅可以作为阴离子掺杂剂，还可以作为有效的形态导向剂。所得PPy纳米线具有长而细的结构，表面光滑，纳米线的平均直径约为90-100 nm，长度为数百纳米至微米。 PPy纳米线的可能形成机制可能与表面带有官能团(-SO - 3 和-COO - )的肝素链状结构有关。研究了吡咯单体和肝素浓度对 PPy 纳米线形态和尺寸的影响。
Heparin, a potent anticoagulant, has been used for the first time for the synthesis of PPy nanowires serving not only as an anion dopant but also as an effective morphology-directing agent. The obtained PPy nanowires exhibit long and fine structures with smooth surface and the average diameter of the nanowires is about 90-100 nm and lengths are several hundred nanometers to micrometers. The possible formation mechanism of PPy nanowires may be related to the chain structure of heparin with functional groups (-SO - 3 and -COO - ) on the surface. The effect of concentrations of pyrrole monomers and heparin on the morphology and size of PPy nanowires has been investigated.
