Abstract

To improve the electrical stability and portability of surface dielectric barrier discharge (SDBD) devices, it is necessary to secure low voltage and low power operations of SDBD. We fabricated polymer SDBD devices using commercial polymer substrates such as polyimide, polyethylene terephthalate. Functional thin film coatings were adapted to protect the degradation of polymer substrate due to reactive oxygen radicals. And the optimization of the electrode structure was conducted to minimize displacement current flow and maximize dissipated power. Several types of electrode such as circular, rectangular, and hexagonal geometry were investigated for SDBD devices. The SDBD showed stable discharge at a low voltage of 2 kV or less, and a pulse frequency of 5-10 kHz. Design parameters of flexible SDBD devices for low voltage and low power operations will be presented.

低电压、低功率自由基片用表面介质阻挡放电装置

为了提高表面介质阻挡放电(SDBD)器件的电气稳定性和便携性，必须保证SDBD器件的低电压、低功耗运行。我们使用商用聚合物衬底如聚酰亚胺、聚对苯二甲酸乙二醇酯制造聚合物SDBD器件。功能薄膜涂层适用于保护活性氧自由基对聚合物基体的降解。并对电极结构进行优化，使位移电流最小，耗散功率最大。研究了几种不同形状的电极，如圆形、矩形和六边形。SDBD在2 kV以下的低电压和5 ~ 10 kHz的脉冲频率下表现出稳定的放电特性。介绍了用于低电压、低功耗工作的柔性SDBD器件的设计参数。下载:下载高分辨率图像(171KB)下载:下载全尺寸图像图1使用表面介质阻挡放电的自由基片的概念下载:下载高分辨率图像(239KB)下载:下载全尺寸图像图2。聚对苯二甲酸乙二醇酯基板的制备
