This study presents a novel flexible, self-adhesive, and high-performance graphene oxide (GO)-modified acrylamide ionogel thermoelectric film. The film is designed to achieve high thermoelectric performance and flexibility, with a Seebeck coefficient of -76.7 mV/K and a power factor of 753.0 μW m⁻¹ K⁻², along with a ZT value of 0.19 at 383 K. The film exhibits excellent flexibility, stretchability, and self-adhesiveness, and can generate an optimal output power density of 1.32 mW cm⁻² with a temperature difference of 20 K, demonstrating its potential for wearable electronics. The film is composed of carbon-based materials, ionic liquids, and cross-linked polymers, and is fabricated through a process involving polymerization, annealing, and integration. The film maintains its thermoelectric and mechanical properties even after 7 days of exposure in the air. The study also highlights the importance of GO in enhancing the film's thermoelectric performance and stability, and demonstrates the potential of the film for long-term, high-performance ionic thermoelectric applications. The results show that the GO-modified ionogel film is a promising candidate for flexible thermoelectric devices, with high efficiency and stability.This study presents a novel flexible, self-adhesive, and high-performance graphene oxide (GO)-modified acrylamide ionogel thermoelectric film.
