Composite transparent conductive electrodes (C-TCEs) have recently been produced using low-cost techniques to keep up with the boom in the fabrication and development of optoelectronic devices. In this article, silver nanowires (AgNWs) were successfully synthesized by a simple hydrothermal method using different molecular weights MWs of poly (N-vinylpyrrolidone) (PVP). Graphene oxide (GO) was prepared using the modified Hummers’ method and a reduction step was held on GO films to produce reduced GO (rGO). C-TCEs were fabricated by over-coating the AgNWs electrodes with rGO, or poly(3,4-ethylenedioxythiophene) polystyrene sulfonate to improve the roughness, surface energy, and sheet resistance. The influence of using lower and higher MWs of PVP on the yield, shape, and size of AgNWs was investigated. The results showed that using lower MW of PVP had a great effect on the yield, morphology, and aspect ratio of AgNWs with diameter of 46 nm and average length 12 µm. The optical, morphological, topographical, and electrical properties of TCEs were studied. AgNWs/rGO composite electrode provided the lowest surface roughness and surface energy of 250 nm and 47.95 mN/m, respectively, with a relatively high transparency of 78.2% at 550 nm light wavelength, and a low sheet resistance of 27 Ω/□.

“…Due to blurriness, TCEs even with high transmittance and high electrical conductivity are not usually considered suitable for optoelectronic display applications. Thus, reducing the haze value to the level of ITO (∼1–3) is necessary for display applications. , Though the electrical conductivity of PEDOT-silica hybrid films slightly decreased as compared to the 5% DMSO treated PEDOT:P(SS- co -AMA) film, the PEDOT-silica hybrid films mainitained very low haze and high visible transmittance due to a lower amount of silica content. The PEDOT-silica hybrid film which contain both TEOS and POTES (sample 11) showed the electrical conductivity of 2.27 s/cm with transmittance of 93.12%.…”

We report a simple approach to enhance the mechanical stability and the hydrophobic property of the poly(3,4ethylenedioxythiophene) (PEDOT) transparent conductive films (TCFs) by an in situ sol−gel hybrid approach. Poly-(styrenesulfonate-co-allyl methacrylate) [P(SS-co-AMA)] was used as a template material to synthesize PEDOT:P(SS-co-AMA) aqueous dispersion. PEDOT:P(SS-co-AMA)/silica hybrid films were then prepared by thiol−ene click and sol−gel reactions using silane precursors like 3-mercaptopropyltrimethoxysilane (MPTMS), tetraethyl orthosilicate (TEOS) and perfluorooctyltriethoxysilane (POTES). Pristine PEDOT:P(SS-co-AMA) films on glass showed the electrical conductivity (σ) of 0.07 S/cm, while secondary doping with 5% DMSO increased the conductivity to 77.13 S/cm (transmittance over 92%). As silica is introduced, the electrical conductivity of the PEDOT:P(SS-co-AMA)/silica hybrid films decreased and was in the range of 2.27−76.20 S/cm. Furthermore, the silica hybrid films showed transmittance, >92%; water contact angle, >100°; and pencil hardness, >6H indicating improved hydrophobic property and mechanical stability due to the cross-linked silica network, perfluoro octyl moiety and good compatibility between the organic/inorganic phases. The PEDOT-silica hybrid films with good transparency and electrical conductivity and superior hydrophobic and mechanical properties are suitable candidates for durable optoelectronic device applications.

A growing number of people are interested in using silver nanowires (AgNWs) as potential transparent and conductive materials. The production of high-performance and high-throughput AgNWs was successfully optimized in this work using a one-step, straightforward, and reproducible modified polyol approach. The factors influencing the morphology of the silver nanowires have undergone extensive research in order to determine the best-optimized approach for producing AgNWs. The best AgNW morphology, with a length of more than 50 m and a diameter of less than 35 nm (aspect ratio is higher than 1700), was discovered to be produced by a mixture of 44 mM AgNO3, 134 mM polyvinylpyrrolidone (PVP) (Mo.Wt 40,000), and 2.4 mM KCl at 160 °C with a stirring rate of 100 rpm. With our improved approach, the overall reaction time was cut from almost an hour with the conventional polyol method to a few minutes. Scanning electron microscopy (SEM), X-ray diffraction (XRD), and ultraviolet (UV) spectroscopy were used to characterize AgNWs. The resultant AgNWs’ dispersion was cleaned using a centrifuge multiple times before being deposited on glass and PET substrates at room temperature. In comparison to commercial, delicate, and pricey indium-doped tin oxide (ITO) substrates, the coated samples displayed exceptionally good sheet resistance of 17.05/sq and optical haze lower than 2.5%. Conclusions: Using a simple one-step modified polyol approach, we were able to produce reproducible thin sheets of AgNWs that made excellent, flexible transparent electrodes.
