Preparation and application of graphene oxide hybrid polyaniline based flexible electrode materials

Flexible electrode materials refer to materials used as electrodes in electronic devices, which have characteristics such as softness, flexibility, and stretchability, and are suitable for the preparation of various flexible electronic devices. In this study, in order to optimize the problems of poor specific capacity, low conductivity, and instability of conventional flexible electrode materials, the performance and reliability of the flexible electrode materials were improved by hybridizing graphene oxide (GO) and polyaniline (PANI). In this paper, graphene oxide - polyaniline (GO-PANI) flexible electrode materials were prepared and tested for their performance using graphene and polyaniline. In the experiments, a current density of 1 A/g was selected for the constant current charge/discharge test of GO-PANI electrode materials with different graphene contents to evaluate the performance of GO-PANI electrode materials in energy storage. After the experiments, it was proved that the charge/discharge times of GO-PANI electrode materials were 1430s, 1625s, and 1495s when the graphene content was 1%, 3% and 5%, respectively, and the GO-PANI (3%) electrode material had the longest charge/discharge time. Accordingly, it can be concluded that GO-PANI (3%) electrode material had the best energy storage performance, which could realize a stable and efficient charging and discharging process, and could be used as an ideal electrode material in flexible electronic devices. The research in this paper could provide new ideas and solutions for the development of flexible electrode materials and promote the further development and application of flexible electronics technology.
