Zinc oxide - polymer interfaces are known to exhibit interesting properties regarding molecular adhesion. This work is aimed at the investigation of the effect of the morphology and surface chemistry on the macroscopic adhesion of a model epoxy-based adhesive to nanorod (ZnO NR) and nanocrystalline (ZnO NC) ZnO-modified surfaces. Both ZnO films have been prepared using hydrothermal synthesis on hot-dip galvanized steel (HDG) surfaces by varying the precursor chemistry in order to control the film morphology. Poly (acrylic acid) (PAA) was used to improve the interfacial adhesion by modifying the morphology and surface chemistry of ZnO nanostructured films. The strong interaction of PAA from a dilute and neutral aqueous solution with the ZnO nanocrystallites was shown to significantly improve the interfacial adhesion by means of a nanoetching process. It was shown that the wet peel-forces correlate well with the considered morphology and surface chemistry.

已知氧化锌-聚合物界面在分子粘附方面表现出令人感兴趣的特性。这项工作旨在调查形态和表面化学对模型环氧树脂基粘合剂对纳米棒（ZnO NR）和纳米晶体（ZnO NC）ZnO改性表面的宏观粘合的影响。两种ZnO膜均通过在热浸镀锌钢（HDG）表面上进行水热合成来制备，方法是改变前驱体的化学性质，以控制膜的形态。聚丙烯酸（PAA）被用来通过改变ZnO纳米结构膜的形态和表面化学来改善界面附着力。稀和中性水溶液中的PAA与ZnO纳米微晶的强相互作用显示出可通过纳米蚀刻工艺显着改善界面粘合力。结果表明，湿剥离力与所考虑的形态和表面化学性质具有良好的相关性。
