氧化锌四脚体（ZnO TP）由于其广泛的应用领域，在过去的几年中已经达到了高度的兴趣。在这里，ZnO TP和聚（丙烯酸）（PAA）的粘合促进性能的组合被证明。以聚丙烯（PP）为模型体系，采用水基分散液快速喷涂法在其表面存款了均匀的纳米复合薄膜。通过场发射扫描电子显微镜（FE-SEM）、高分辨X射线光电子能谱（XPS）和透射电子显微镜（TEM）对ZnO薄膜进行了表征。PP/PP层压板与界面ZnO TP/PAA膜表现出的剪切强度值的增加，可以归因于ZnO TP的机械联锁和PAA的大分子粘附促进。剪切试验后的FE-SEM成像表明ZnO TP的芯部失效。通过PP箔的等离子体活化和具有低浓度的0.085 mM PAA和8 mg/ml ZnO TP的复合膜的喷涂的快速应用方法使得该技术对于工业应用相当有趣。
Zinc oxide tetrapods (ZnO TP) have reached a high level of interest in the last years due to their broad fields of applications. Here, the combination of the adhesion promoting properties of both ZnO TP and poly(acrylic acid) (PAA) is demonstrated. A very rapid spray coating of water-based dispersions has been used to deposit homogenous thin nanocomposite films on poly(propylene) (PP) foils considered as model system. The characterization of ZnO TPs has been carried out by field-emission scanning electron microscopy (FE-SEM), high-resolution X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy (TEM). The increased shear strength values exhibited by PP/PP laminates with interfacial ZnO TP/PAA films could be attributed to mechanical interlocking of ZnO TP and the macromolecular adhesion promotion by PAA. FE-SEM imaging after shear tests indicated a failure in the core of the ZnO TP. The fast application method via plasma activation of the PP foils and spray coating of the composite films with low concentrations of 0.085 mM PAA and 8 mg/ml ZnO TP makes this technique rather interesting for industrial applications.
