The modification of surface properties of isotactic polypropylene (it.PP) has attracted much attention in fundamental science and industrial applications. Primer treatment is a promising methods that is employed to overcome the poor adhesive property of it.PP. In this study, we examined the primer effect of the cobalt complexes, cobalt (II) acetylacetonate Co(acac)₂ and cobalt (III) acetylacetonate Co(acac)₃, from the perspectives of adhesive strength, curing process, surface structure, affinity between substrate and adhesive, morphology and interfacial thickness. The results obtained explain the increased adhesive strength between an isotactic polypropylene substrate and a cyanoacrylate adhesive. In particular, the interfacial regions were evaluated as “interphase” by nano-Raman scattering microscopy and transmission electron microscope-energy-dispersive X-ray spectroscopy. The region is expanded by applying Co(acac)₂ primer as the adhesive strength increased. The Co(acac)₂ primer caused the increased adhesive property with the enhancement of molecular interaction, chemical affinity, and mutual diffusion.

表面性质的改变等规聚丙烯（它.PP）备受关注基础科学和工业应用。底漆处理是一种有前途的方法，可用来克服其较差的粘合性能。PP。在这项研究中，我们从粘合强度，固化过程，表面结构，亲和力的角度研究了钴配合物乙酰丙酮钴（II）Co（acac）₂和乙酰丙酮钴（III）Co（acac）₃的底漆效果。在基材和粘合剂之间，形态和界面厚度之间的关系。获得的结果解释了等规立构之间粘合强度的提高聚丙烯基材和氰基丙烯酸酯粘合剂。特别地，通过纳米拉曼散射显微镜和透射电子显微镜-能量分散X射线光谱法将界面区域评价为“界面相”。随着粘合强度的增加，通过涂覆Co（acac）₂底漆可扩大区域。Co（acac）₂底漆通过增加分子相互作用，化学亲和力和相互扩散而增强了粘合性能。
