Owing to their high strength and stiffness, thermal and environmental stability, lower shrinkage, and water resistance, epoxy resins have been the preferred matrix for the development of syntactic foams using hollow glass microspheres. Although these foams are exploited in multiple applications, one of their issues is the possibility of breakage of the glass hollow microspheres during processing. Here, we present a straightforward and single-step foaming protocol using expandable polymeric microspheres based on the well-established compression molding process. We demonstrate the viability of the protocol producing two sets of nanocomposite foams filled with carbon-based nanoparticles with improved transport properties.
由于环氧树脂具有高强度、高刚度、热稳定性和环境稳定性、低收缩率以及耐水性，它们一直是使用空心玻璃微珠开发复合泡沫材料时的首选基体。尽管这些泡沫材料有多种应用，但其中一个问题是在加工过程中玻璃空心微珠可能会破裂。在此，我们基于成熟的压缩成型工艺，提出了一种使用可膨胀聚合物微球的简单单步发泡方案。我们证明了该方案能够生产出两组填充碳基纳米颗粒且具有改善传输性能的纳米复合泡沫材料。
