Dielectric, Ferroelectric, and Electric Applications of Polymers: Recent Advances and Progress

ABSTRACT Polymers with electric, dielectric, and ferroelectric properties have become essential materials in a wide range of modern technologies, from flexible electronics and energy storage systems to biomedical devices and smart sensors. Their inherent mechanical flexibility, chemical tunability, lightweight nature, and processability enable their integration into advanced functional materials with tailored performance. In particular, dielectric polymers are widely used in capacitors and insulation layers, ferroelectric polymers provide spontaneous polarization for memory and sensing applications, and conductive polymers serve as flexible alternatives to metallic conductors. This review presents a comprehensive overview of the recent advances and emerging trends in the field of electric, dielectric, and ferroelectric polymeric materials. It discusses the fundamental principles and structural considerations that define their performance, followed by an exploration of their role in six critical application areas: energy storage, wearable electronics, piezoelectric sensors, capacitors, flexible displays, and biomedical systems. Through the integration of recent studies and technological breakthroughs, this review aims to bridge the gap between materials science and device engineering, while highlighting key challenges, current limitations, and promising strategies for future development. The paper concludes with forward‐looking perspectives on how next‐generation polymer systems can be designed to address pressing societal and industrial needs.
