Abstract

A glass substrate, coated with a Parylene film, was coated with ZnO by three different methods: ultrasound, microwave, and microwave-plasma irradiation. These coating modes are simple, efficient, and environmentally friendly one-step processes. The structure of the coated products was characterized and compared using methods such as XRD, HR-SEM, EDS, RBS, and optical spectroscopy. Coating by ZnO nanoparticles was achieved for all three approaches. The products were found to differ in their particle sizes, coating thickness, and depth of penetration. All of the ZnO-Parylene-glass composites demonstrated a significant antibacterial activity against Escherichia coli (Gram negative) and Staphylococcus aureus (Gram positive) strains.

摘要

一个涂有聚对二甲苯薄膜的玻璃基底，通过三种不同的方法涂覆了氧化锌：超声、微波和微波等离子体辐照。这些涂覆模式简单、高效且环保，是一步法工艺。使用 XRD、高分辨率扫描电子显微镜（HR-SEM）、能谱仪（EDS）、RBS 和光谱学等方法对涂覆产品的结构进行了表征和比较。所有三种方法都实现了 ZnO 纳米颗粒的涂覆。发现产物在粒径、涂层厚度和渗透深度方面存在差异。所有 ZnO-聚对二甲苯-玻璃复合材料对大肠杆菌（革兰氏阴性）和金黄色葡萄球菌（革兰氏阳性）菌株均表现出显著的抗菌活性。
