Abstract
We prepared polyaniline-poly(4-styrenesulfonate) nanoparticles (PANI/PSS-NPs) by chemical oxidation polymerization in aqueous solution. We investigated the potential of the PANI/PSS-NPs to be used as an anode electrode for electrochromic devices and the effect of Li+ insertion (or deinsertion) kinetics and diffusion of Li+. A uniform electrochromic layer of PANI/PSS-NPs with a size of ca. 28 nm could be obtained by a solution process, specifically spin coating. The PANI/PSS-NPs film has a high Li+ diffusion coefficient (∼7.7 × 10−9 cm2 s−1) and low charge transfer resistance (∼99 Ω), which result in its having a fast electrochromic response time (coloring time <1.7 s, bleaching time <2.4 s), and high coloration efficiency (>108 cm2 C−1).
