Special Issue Information

Dear Colleagues,

This Special Issue is motivated by the growing interest in the design, fabrication, and application of polymer-based electronic devices and sensors. In recent years, a variety of polymer-based compounds have been developed. Their novel chemical and physical properties extend their applications in different fields. As external stimuli, including pH, light radiation, heat, etc., are further applied to polymer-based materials, they may have reversible or irreversible changes in their physical and chemical properties.

This Special Issue on “Polymer Based Electronic Devices and Sensors” will collect new original research and review papers, with a special emphasis on the improved properties, innovative fabrication processes, and novel applications of functional polymer composites. We warmly invite researchers in this field to submit relevant manuscripts to this Special Issue of Polymers.

Graphene-based materials have been widely studied in the field of supercapacitors. However, their electrochemical properties and applications are still restricted by the susceptibility of graphene-based materials to curling and agglomeration during production. This study introduces a facile method for synthesizing reduced graphene oxide (rGO) nanosheets and activated carbon based on olive stones (OS) with polyaniline (PAni) surface decoration for the development of supercapacitors. Several advanced techniques were used to examine the structural properties of the samples. The obtained PAni@OS−rGO (1:1) electrode exhibits a high electrochemical capacity of 582.6 F·g−1 at a current density of 0.1 A·g−1, and an energy density of 26.82 Wh·kg−1; thus, it demonstrates potential for efficacious energy storage. In addition, this electrode material exhibits remarkable cycling stability, retaining over 90.07% capacitance loss after 3000 cycles, indicating a promising long cycle life. Overall, this research highlights the potential of biomass-derived OS in the presence of PAni and rGO to advance the development of high-performance supercapacitors. Full article

In wearable bioelectronics, various studies have focused on enhancing prosthetic control accuracy by improving the quality of physiological signals. The fabrication of conductive composites through the addition of metal fillers is one way to achieve stretchability, conductivity, and biocompatibility. However, it is difficult to measure stable biological signals using these soft electronics during physical activities because of the slipping issues of the devices, which results in the inaccurate placement of the device at the target part of the body. To address these limitations, it is necessary to reduce the stiffness of the conductive materials and enhance the adhesion between the device and the skin. In this study, we measured the electromyography (EMG) signals by applying a three-layered hydrogel structure composed of chitosan–alginate–chitosan (CAC) to a stretchable electrode fabricated using a composite of styrene–ethylene–butylene–styrene and eutectic gallium-indium. We observed stable adhesion of the CAC hydrogel to the skin, which aided in keeping the electrode attached to the skin during the subject movement. Finally, we fabricated a multichannel array of CAC-coated composite electrodes (CACCE) to demonstrate the accurate classification of the EMG signals based on hand movements and channel placement, which was followed by the movement of the robot arm.

Lithium-ion batteries (LIBs) have become indispensable energy-storage devices for various applications, ranging from portable electronics to electric vehicles and renewable energy systems. The performance and reliability of LIBs depend on several key components, including the electrodes, separators, and electrolytes. Among these, the choice of binder materials for the electrodes plays a critical role in determining the overall performance and durability of LIBs. This review introduces polymer binders that have been traditionally used in the cathode, anode, and separator materials of LIBs. Furthermore, it explores the problems identified in traditional polymer binders and examines the research trends in next-generation polymer binder materials for lithium-ion batteries as alternatives. To date, the widespread use of N-methyl-2-pyrrolidone (NMP) as a solvent in lithium battery electrode production has been a standard practice. However, recent concerns regarding its high toxicity have prompted increased environmental scrutiny and the imposition of strict chemical regulations. As a result, there is a growing urgency to explore alternatives that are both environmentally benign and safer for use in battery manufacturing. This pressing need is further underscored by the rising demand for diverse binder research within the lithium battery industry. In light of the current emphasis on sustainability and environmental responsibility, it is imperative to investigate a range of binder options that can align with the evolving landscape of green and eco-conscious battery production. In this review paper, we introduce various binder options that can align with the evolving landscape of environmentally friendly and sustainable battery production, considering the current emphasis on battery performance enhancement and environmental responsibility.

The ever-increasing demand for faster computing has led us to an era of heterogeneous integration, where interposers and package substrates have become essential components for further performance scaling. High-bandwidth connections are needed for faster communication between logic and memory dies. There are several limitations to current generation technologies, and dielectric buildup layers are a key part of addressing those issues. Although there are several polymer dielectrics available commercially, there are numerous challenges associated with incorporating them into interposers or package substrates. This article reviewed the properties of polymer dielectric materials currently available, their properties, and the challenges associated with their fabrication, electrical performance, mechanical reliability, and electrical reliability. The current state-of-the-art is discussed, and guidelines are provided for polymer dielectrics for the next-generation interposers. Full article
