【摘要】 装饰性薄膜应用领域非常广泛。其一般设计方法是滤光膜系设计法，这种方法不仅繁琐，而且所需的膜层数多，实际生产中需要很高的镀膜工艺技术。本文重点讨论一种改进的塑料基材装饰性薄膜设计法，并解决了薄膜制备过程中遇到的一些关键性问题。以薄膜干涉理论为基础，导出了薄膜干涉产生的颜色与膜厚间关系，并据此设计出比较简单的膜系结构，降低了对镀膜工艺的要求；在磁控溅射制备单质金属(如Al、Ni、Cr)装饰膜以及彩色装饰膜过程中，通过对薄膜膜厚均匀性影响因素的分析，调整工艺参数，解决了镀制高透薄膜时，由于膜厚均匀性而引起的生产率下降问题；从光学塑料的特性出发，通过薄膜附着力理论分析，改变工艺参数，解决了Al膜与塑料基材附着力差的问题；通过薄膜膜系应力理论分析，提出在彩色装饰膜系中的金属膜表面镀制一层致密介质薄膜，结果不仅保护了金属膜，减少了潮气影响，还可以使整个膜系所受的应力减少，有效改善了薄膜附着力。更多还原

【Abstract】 Decorative coatings have found wide application in practice. Usually these coatings are designed with filter method which is very complicated, and the structures of designed stacks are complex and prove hard for production. This paper mainly focuses on a new design method for decorative coatings deposited on plastic substrate, and solves some key technical problems encountered in the fabrication of the coatings. Based on the theory of thin film interference, the relationship between the reflective color and film thickness is deduced and corresponding multilayer is designed. The newly designed stack is much simple and can be easily made in mass-production scale. Metallic decorative film (Al, Ni and Cr) and colorful decorative film are prepared by magnetron sputtering technique. Based on the analysis of the factors that affect thickness uniformity, some technical parameters related to the film production are adjusted and uniform film is acquired, thus significantly raises the productivity of the deposition of metallic film with high transmissivity on plastic substrates. By analysis of the characteristics of the plastic substrate and utilization of film adhesion theory, the adhesion between Al and substrate is greatly improved in the production of magnetron sputtering metallic Al film. Since metallic film is the outmost layer of the colorful decorative multilayer, compact dielectric film is over coated on its surface to protect the metallic film from the erosion of moister. The addition of the dielectric film can also reduce the stress of the stack, therefore improve the adhesion of the film.更多还原
