A review on the electrically conductive transparent polymer composites: Materials and applications

Abstract

Polymer composites have advanced tremendously in recent decades as the outcome of notable investigations. Among these advances, electrically conductive transparent polymer composites (ECTPCs) have emerged as a potential family of materials that combine electrical conductivity with optical transparency. ECTPCs have a wide range of possible applications, including optoelectronics, solar cells, touch screens, smart windows, and more. This paper gives a complete summary of the most recent advances in the manufacture, characterization, and applications of ECTPCs. The article discussed the various conductive filler materials used in ECTPCs, including metal powder, carbon nanotubes (CNTs), and graphene alongside their incorporation methods into the transparent polymer matrix. Additionally, the factors influencing the electrical conductivity and optical transmittance of ECTPCs are thoroughly discussed, accompanied by a detailed description of characterization techniques. Despite the immense potential of ECTPCs, it is important to consider the challenges and limitations. Thus, the review addresses these concerns, including the need to strike a balance between electrical conductivity and optical transparency while ensuring long-term stability. Moreover, the future prospects for the development and practical applications of ECTPCs are explored, highlighting potential avenues for further research and advancements in this field. Overall, this review offers valuable insight into the latest advances in ECTPCs, their methods of fabrication, methods of characterization, and possible applications. By addressing challenges and outlining future directions, the current article contributes to the ongoing progress and paves the way for the practical implementation of ECTPCs in various industries.
