环氧树脂是一类非常重要的结构胶粘剂，人们一直在寻求性能的改进。由于聚合物和纳米颗粒表面之间的相互作用只是粘附性，因此通过添加具有定制表面的纳米颗粒显然有改善性能的空间。颗粒团聚、表面化学以及颗粒-聚合物界面的厚度和组成对所产生的材料性能至关重要。此外，同时使用不同的纳米颗粒可以显著改善性能。特定的纳米颗粒带来了新的功能。这一点在用于快速固化粘合剂的“天线颗粒”中得到了验证。
Epoxy resins are a very important class of structural adhesives and property improvements are constantly being sought. As the interaction between the polymer and the surface of nanoparticles is nothing other than adhesion, there is obvious scope for property improvements by adding nanoparticles having tailored surfaces. Particles agglomeration, surface chemistry, and the thickness and composition of the particle-polymer interphase are crucial for the resulting material properties. Also, the simultaneous use of different nanoparticles can lead to marked property improvements. Specific nanoparticles lead to new functions. This is demonstrated for "antenna particles" for rapid-curing adhesives.
