纳米尺度的导电聚合物赋予材料特殊的光学、电学和磁性。构建和调控CPS微观结构的关键因素是诱导剂,特别是其化学结构、活性部位、自组装特性。在本论文中,我们设计并合成了骨架上含有四唑基团的两亲分子,并以此为诱导剂制备并调节了一系列CPS的微结构,包括聚吡咯、聚苯胺、聚(3,4-乙二氧基噻吩基)和聚对苯二胺。由于CPS独特的电学性质和尺寸效应,我们接下来研究了这些CPS纳米结构的电磁吸收性能。用电损耗和磁损耗的协同组合解释了这些CPS纳米结构的吸收机理。
Conducting polymers (CPs) at nano scales endow materials with special optical, electrical, and magnetic properties. The crucial factor to construct and regulate the micro-structures of CPs is the inducing reagent, particular in its chemical structure, such active sites, self-assembling properties. In this paper, we design and synthesize an amphiphile bearing tetrazole moiety on its skeleton, and use this amphiphile as an inducing reagent to prepare and regulate the micro-structures of a series of CPs including polypyrrole, polyaniline, poly(3,4-ethylenedioxythiophene) and poly(p-phenylenediamine). Because of the unique electric properties of CPs and size effect, we next explored the electromagnetic absorption performances of these CPs nanostructures. A synergetic combination of electric loss and magnetic loss is used to explain the absorption mechanism of these CPs nano-structures.
