The soft portable electronic equipment, such as rollup displays and wearable devices, requires the development of flexible energy sources. Among them, a bendable battery needs soft electrode materials. Polyaniline (PANI) has been examined as an electrode material, on the basis of reversible doping behavior, inexpensive cost, and low self-discharge rate. However, PANI has some shortcomings of poor processability and performance. So many efforts have been made to improve the electrochemical property by controlling the microstructure in order to increase the surface area of electrode and electrolyte. Here, porous PANI and polyvinyl alcohol (PVA) composites were prepared by emulsion polymerization. PVA was chosen as a supporting material to make porous structure and increase the flexibility. And the characterizations of the polymer electrode were carried out by means of FT-IR, UV-Vis spectra, scanning electron microscopy (SEM), and X-ray diffraction. |
