The paper described here concerns a challenge of general interest for producing a novel structure of a polymer aggregate, the achievement of nanowires with controlled diameters. We provide a strategy for fabricating a supramolecular polymer, in which ordered polydiacetylene nanowires can be obtained by associated self-polymerization and self-assembly processes. The polymer nanowire film shows excellent field emission properties with the turn-on field of 8.2 V/mum at 10 muA/cm2 and the maximum current density of 5 mA/cm2 at an applied field of 15 V/mum.
本文所述的论文涉及一个具有普遍意义的挑战，即制备聚合物聚集体的新型结构，也就是实现具有可控直径的纳米线。我们提供了一种制备超分子聚合物的策略，通过相关的自聚合和自组装过程可以获得有序的聚二乙炔纳米线。该聚合物纳米线薄膜表现出优异的场发射性能，在10 μA/cm²时的开启场为8.2 V/μm，在15 V/μm的外加场下最大电流密度为5 mA/cm²。
