Special Issue Information

Dear Colleagues,

Polymers have been instrumental in the development of novel and highly functional materials for applications in the fields of optics and electronics. Through the meticulous design and functionalization of polymer structures, it is possible to achieve diversity of optical and electronic properties that align with various engineering objectives. This chemical versatility renders polymers promising candidates for fulfilling future demands for enhanced functionality such as flexibility, stretchability, biocompatibility, and processibility. This Special Issue endeavors to compile original ideas and discoveries in functional polymer science and technology on optics and electronics, as well as provide systematic synopses of recent remarkable achievements. The scope encompasses functional polymers for opto/electronic devices, sensors, photocatalysts, energy harvesting, and storage systems. Submissions of original research articles, review articles, communications, and perspectives that present recent trends in these domains are encouraged.

This study details the development and validation of a graphene-based ice detection system, designed to enhance flight safety by monitoring ice accumulation on aircraft surfaces. The system employs a semiconductive polymer (PEDOT:PSS) with graphene electrodes, interpreting resistance changes to detect water impact and ice formation in real time. The sensor’s performance was rigorously tested in a wind tunnel under various temperature and airflow conditions, focusing on resistance signal dependency on air temperature and phase change. The results demonstrate the sensor’s ability to distinguish water droplet impacts from ice formation, with a notable correlation between resistance signal amplitude and water droplet impacts leading to ice accretion. Further analysis shows a significant relationship between air temperature and the resistance signal amplitude, particularly at lower temperatures beneficial to ice formation. This underlines the sensor’s precision in varied atmospheric conditions. The system’s compact design and accurate detection highlight its potential for improving aircraft ice monitoring, offering a path toward a robust and reliable ice detection system. Full article

Multifunctional wearable devices detect electric signals responsive to various biological stimuli and monitor present body motions or conditions, necessitating flexible materials with high sensitivity and sustainable operation. Although various dielectric polymers have been utilized in self-powered wearable applications in response to multiple external stimuli, their intrinsic limitations hinder further device performance enhancement. Because triboelectric devices comprising dielectric polymers are based on triboelectrification and electrostatic induction, multilayer-stacking structures of dielectric polymers enable significant improvements in device performance owing to enhanced interfacial polarization through dissimilar permittivity and conductivity between each layer, resulting in self-powered high-performance wearable devices. Moreover, novel triboelectric polymers with unique chemical structures or nano-additives can control interfacial polarization, allowing wearable devices to respond to multiple external stimuli. This review summarizes the recent insights into multilayered functional triboelectric polymers, including their fundamental dielectric principles and diverse applications. Full article
