- Abstract
- Commercial flat-panel detectors (FPDs) are fragile, and they can easily be damaged when external mechanical impact is applied. To address this problem, considerable time and effort have been devoted to researching FPDs, but current studies have yet to provide solutions. In this paper, our study focused on developing a bendable digital detector for improvement of mechanically stable. We present the fabrication and measurement of the bendable X-ray detector based on PbI2; it can be fabricated via segmentation method and screen printing method. The result of experiment, detector production using the screen-printing method negatively impacts bendable properties due to porosity, which is generated due to existing moisture in the sensor layers, causing 'stress concentration' In addition, this study finds a direction relationship between porosity and electrical properties; this study demonstrates that porosity has a proportional relationship to the particle filling factor. More specifically, controlling the binder amount decreases these electrical properties. This research confirms that controlling the binder amount is an inappropriate measure for developing bendable properties and recommends further studies on the topic. Therefore, future research should focus on methods for producing polymer for improved of cross-link efficiency.
