Flexible electronic devices have attracted immense attention in recent years. Conventional electronics that are predominantly fabricated with rigid metallic materials demonstrate poor flexibility. Compared to traditional electronic devices, flexible electronic devices with better flexibility can adapt to different working environments. Consequently, they fit perfectly with different systems with minimal rejections. However, such flexible electronic devices need to achieve good extensibility and flexibility without compromising on their electronic properties. Therefore, new challenges and requirements arise while fabricating conductive materials. Manufacturing of flexible metal electrodes for flexible electronic devices include strategies such as reducing the thickness of the electrodes and designing electrodes with unique structures. However, these technologies are complex and expensive. Carbon nanotube(CNT) films exhibit good flexibility, excellent conductivity, good chemical and thermal stability, as well as good optical transparency, making them ideal candidates for flexible electronics. Therefore, the preparation and application of CNT films for the development of next generation flexible electronics have been extensively studied. In this review, we summarize the recent advances in the preparation of CNT films and their application in flexible electronic devices. Initially, the two main kinds of preparation methods for CNT films-dry and wet methods-are introduced. The dry methods for CNT film preparation include the membrane extraction method based on a vertical array of CNTs and the floating catalytic chemical vapor deposition method. Moreover, the wet methods predominantly discussed include vacuum filtration method, impregnation method, electrodeposition method, self-assembly method, and spraying method. Subsequently, the latest research advancements in assembly techniques, their performance and applications in various flexible electronics are discussed. This review primarily introduces the application of C
