摘要

硫酸是电子设备触点的一个隐患,而将无定形碳薄膜用作小型线圈的薄电绝缘涂层需要对其影响进行充分研究。在不同的沉积条件下,利用真空镀膜系统在硅基底上制备了五种非晶碳薄膜。根据其光学常数(ISO 23216:2021(E)),这些薄膜被分为三种类型:氢化无定形碳(a-C:H)、类聚合物碳(PLC)和类石墨碳(GLC)。对薄膜在硫酸中浸泡前后的结构、表面成分和电绝缘性能进行了评估。虽然 PLC 和 a-C:H 因硫酸浸泡而出现表面氧化,但其结构和直流介电击穿场强均未因硫酸浸泡而发生明显变化,这证明了它们的稳定性。此外,消光系数相对较低的 PLC 和 a-C:H 还具有出色的绝缘性能。我们的研究结果表明,无定形碳薄膜可用作可能与硫酸接触的小型线圈的绝缘薄膜。我们的研究为工业界的普通用户提供了一个有价值的工具,便于他们根据消光系数等光学常数选择电绝缘非晶碳薄膜。

Effect of Sulfuric Acid Immersion on Electrical Insulation and Surface Composition of Amorphous Carbon Films
Sulfuric acid is a concern for contacts within electronic devices, and the application of amorphous carbon films as thin electrical insulating coatings for small coils requires full investigation of its effects. Five types of amorphous carbon films were fabricated on Si substrates under different deposition conditions using vacuum coating systems. Based on their optical constants (ISO 23216:2021(E)), the films were classified into three types: hydrogenated amorphous carbon (a-C:H), polymer-like carbon (PLC), and graphite-like carbon (GLC). The structure, surface composition, and electrical insulation properties of the films were evaluated before and after immersion in sulfuric acid. Although the PLC and a-C:H showed progression of surface oxidation due to sulfuric acid immersion, none showed obvious changes in their structure or DC dielectric breakdown field strength due to sulfuric acid immersion, proving their stability. Furthermore, the PLC and a-C:H, which had a relatively low extinction coefficient, exhibited excellent insulation properties. Our results suggest that amorphous carbon films can be useful as thin insulating films for small coils that may come in contact with sulfuric acid. Our study offers a valuable tool for general users in the industry to facilitate selection of electrical insulating amorphous carbon films based on optical constants, such as extinction coefficients.

期刊介绍: Coatings is an international, peer-reviewed open access journal of coatings and surface engineering. It publishes reviews, research articles, communications and technical notes. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. Full experimental and/or methodical details must be provided. There are, in addition, unique features of this journal: * manuscripts regarding research proposals and research ideas will be particularly welcomed * electronic files or software regarding the full details of the calculation and experimental procedure - if unable to be published in a normal way - can be deposited as supplementary material
