Polystyrene applications in organic electronics

Abstract

Abstract Organic electronics represent a promising frontier in the research and development of flexible, lightweight, and cost-effective electronic devices. However, their broader adoption is currently impeded by several critical challenges, including material stability, low charge carrier mobility, difficulties in controlling crystallization and morphology, and overall device reliability. This article provides a detailed analysis of these challenges, and discusses how they affect the performance and longevity of organic electronic devices. It then explores the incorporation of polystyrene (PS) as a polymer additive, highlighting its effectiveness in mitigating these issues. PS, when blended with organic semiconductor materials, has been shown to significantly enhance device performance by improving molecular ordering, reducing defect density, and stabilizing interfaces. In thin film transistors, PS contributes to better mechanical stability and higher charge carrier mobility by promoting favorable phase segregation and crystallization. In phototransistors and sensors, PS enhances sensitivity and selectivity while also improving environmental resistance. Additionally, in memory devices, PS facilitates better charge storage and retention characteristics. This article underscores the critical role of PS in advancing organic electronics, and demonstrates how its strategic use can overcome some of the most persistent challenges in the field, paving the way for unlocking the full potential of organic electronic devices in commercial applications.
