将纳米颗粒掺入聚合物中是一种设计方法，在材料科学的许多领域中都有使用。这一概念很有吸引力，因为它能够通过混合多种成分和利用协同效应来创造具有新的或改进的性能的材料。一个重要的技术推动力是开发具有改进的机械和热特性的结构材料。同样耐人寻味的是设计具有独特光学或电子性能、催化活性或选择性渗透的功能材料的可能性。然而，由于缺乏控制纳米颗粒分散的有效方法，聚合物纳米复合材料的广泛技术开发受到了阻碍。我们报道了一种简单而通用的形成均质聚合物/纳米纤维复合材料的工艺。该方法是基于形成个性化良好的纳米纤维的三维模板，其中填充着任何选择的聚合物。我们证明，这种模板方法是广泛适用的，并允许制造原本无法获得的不相容组分的纳米复合材料。
The incorporation of nanoparticles into polymers is a design approach that is used in many areas of materials science. The concept is attractive because it enables the creation of materials with new or improved properties by mixing multiple constituents and exploiting synergistic effects. One important technological thrust is the development of structural materials with improved mechanical and thermal characteristics. Equally intriguing is the possibility to design functional materials with unique optical or electronic properties, catalytic activity or selective permeation. The broad technological exploitation of polymer nanocomposites is, however, stifled by the lack of effective methods to control nanoparticle dispersion. We report a simple and versatile process for the formation of homogeneous polymer/nanofibre composites. The approach is based on the formation of a three-dimensional template of well-individualized nanofibres, which is filled with any polymer of choice. We demonstrate that this template approach is broadly applicable and allows for the fabrication of otherwise inaccessible nanocomposites of immiscible components.
