Research and Application of Functional Polymer Materials in Flexible Electronics

Flexible electronics technology has emerged as a transformative technology and is developing rapidly. However, traditional metals and inorganic semiconductors face limitations in flexible devices due to poor stretchability and adaptability. Polymers, with their lightweight, flexible, and multifunctional properties, are considered key materials for the fabrication of flexible electronic devices. Additionally, functional polymer materials offer tunable chemical structures, low cost, and compatibility with solution processing techniques, playing a significant role in enabling lightweight, stretchable, and wearable devices. This paper reviews recent advances in the design, synthesis, and integration of conductive, dielectric, piezoelectric, self-healing, biodegradable, and two-dimensional material-enhanced polymers. Additionally, the applications of functional polymer materials in flexible electronics are discussed. Finally, the challenges faced by functional polymer materials in flexible electronics are analyzed, and feasible future development directions are explored.
