“…Furthermore, response time of the electrochromic devices has also been calculated. The response time of electrochromic devices can be defined as the time needed for 80% of the current density change since the moment at which the new voltage is applied [35]. The response time for the RGO/Au grid based device is $60 ms, which is much faster than that of ITO electrodes based device ($330 ms) (Fig.…”

Poly(3,4-ethylenedioxythiophene) (PEDOT) nanoparticles were synthesized via chemical oxidation polymerization using 3,4-ethylenedioxythiophene as the starting monomer and ammonium peroxydisulfate (APS) as the oxidant. The effects of APS concentration, surfactant concentration and type of surfactant, namely dodecylbenzenesulfonic acid and sodium dodecylsulfate, were investigated. Distinct particle shapes were obtained: irregular, raspberry agglomerate, coralliform, orange-peel, globular and plum shapes. The particle sizes and the electrical conductivity are in the ranges 60 to 900 nm and <1 to 153 S cm −1 , respectively, depending on the polymerization conditions. PEDOT synthesis in the absence of a surfactant yields a smaller particle size because a larger amount of initiator induces lower molecular weights and smaller PEDOT particles. The smaller PEDOT particles correspond to higher electrical conductivity because of the larger surface areas for electron transfer and a smaller amount of obstructing surfactant aliphatic segments. Moreover, particle size and shape can be varied, depending on surfactant type and concentration which dictate the micellar shapes in the polymerization reaction. This work is focused on the tailor-made PEDOT shape and property relationship under synthesis conditions where several shapes have not been previously seen.

Since their discovery, electrically conductive polymers have gained immense interest both in the fields of basic and applied research. Despite their vast potential in the fabrication of efficient, flexible, and low-cost electronic and optoelectronic devices, they are often difficult to process by wetchemical methods due to their very low to poor solubility in organic solvents. The use of vapor-based synthetic routes, in which conductive polymers can be synthesized and deposited as a thin film directly on a substrate from the vapor phase, provides many unique advantages. This article discusses oxidative vapor deposition processes, primarily vapor phase polymerization and oxidative chemical vapor deposition, of conjugated polymers and their applications. The mild operating conditions (near room temperature processing) allow conformal and functional coatings of conjugated polymers on delicate substrates.
