“…Plasma polymerization is found to be an outstanding method for the preparation of high quality polymer films from different monomers precursors without requiring the use of solvents and additives. Moreover, plasma polymerization processes are faster compared to the traditional methods that demand multi-step process [23].To improve electrochromic and optical prop-erties of new generation flexible devices, V 2 O 5 -PEDOT hybrid film was used as working electrode. In addition, the counter electrode effects were investigated.…”

Vanadium oxide/poly (3,4‐ ethylenedioxythiophene)(V2O5‐PEDOT) hybrid materials were prepared in a rotating quartz plasma reactor via capacitively coupled radio frequency (RF 13.56 MHz) plasma. Thin films of V2O5‐PEDOT hybrid and V2O5 were obtained by electron beam evaporation technique onto flexible PET substrate for electrochromic devices (ECDs) applications. As a counter electrode, both RF magnetron sputtered MoO3 onto ITO coated PET and only ITO coated PET electrodes were used. Characterizations of the films were carried out via using scanning electron microscopy‐energy dispersive X‐ray spectroscopy (SEM‐EDX) and X‐ray diffraction (XRD). Hybrid ECDs results showed that synergistic effect depending on improved stability between V2O5 and PEDOT. As a result, we developed all solid complementary electrochromic devices including V2O5, V2O5‐PEDOT and MoO3 films. The electrochromic device characteristics such as electrochromic contrast, coloration efficiency, switching time were calculated from optical and electrochemical measurements. The highest coloration efficiency and optical contrast were obtained as 53 cm2/C and 17 % for V2O5‐PEDOT/MoO3‐based ECD.

“…In homopolymer cases (cases I and V) of Figure 2 a, both cases have the common peaks at 965, 1061, 2888, 2927 cm −1 . The peaks at 965 cm −1 and 1061 cm −1 are due to the C–H out-plane and in-plane bending vibration from aromatic ring such as benzenoid, quinoid, and thiophene ring, respectively [ 26 , 27 , 28 , 29 , 30 ]. The assigned peaks at 2888 cm −1 and 2927 cm −1 are attributed to the aliphatic of C–H stretching within polymer chain [ 28 ].…”

Synthesis and Properties of Thiophene and Aniline Copolymer Using Atmospheric Pressure Plasma Jets Copolymerization Technique

et al. 2020

This paper investigates the properties of thiophene and aniline copolymer (TAC) films deposited by using atmospheric pressure plasma jets copolymerization technique relative to various blending ratios of aniline and thiophene monomer for synthesizing the donor–acceptor conjugated copolymers. Field emission scanning electron microscopy (FE-SEM) and atomic force microscopy are utilized to measure the surface morphology, roughness and film thickness of TAC films. Structural and chemical properties of TAC films are investigated by Fourier transforms-infrared spectroscopy (FT-IR), time of flight secondary ion mass spectrometry, and X-ray photoelectron spectroscopy. FE-SEM images show that the film thickness and nanoparticles size of the TAC films increase with an addition thiophene monomer in the aniline monomer. FE-SEM, FT-IR results show that TAC films are successfully synthesized on glass substrates in all cases. The iodine doped TAC film on the Si substrate with interdigitated electrodes shows the lowest electrical resistance at blending condition of thiophene of 25%.

“…Where gas phase processes depend on the energy per molecule and result in the formation of comparable reactive chemistries in APP and PECVD, precursor molecules will be subject to orders‐of‐magnitude more collisions while traversing the glow region in APP, leading to markedly different surface processes, and thus affecting chemical, mechanical and morphological characteristics of the films . These properties can have significant implications for the optical transparency or conductivity of thin films, such as polyaniline and polythiophene . [74a,219]…”
