Conductive sol–gel films

Low-temperature sol–gel synthesis of crystalline materials

“…In that work, four key parameters of these lms were determined: conductivity comparable to ITO analog, excellent electrostability, high exibility and exceptional adhesion to the substrate. Results obtained in the this work 142 are of great interest, not only from the point of view of producing promising materials for exible electronics, but also because they are actually precursors for creating absolutely new devices. Entrapping an organic dopant into a crystalline sol-gel matrix allows the development of new sensors for bio-application (due to biocompatibility of boehmite and silver), as well as electrochromic coatings, solar cell elements, accumulators and supercondensers (due to crystalline anatase in the AgNW@TiO 2 composite).…”

“…For example, Reeja-Jayan et al were the rst to perform microwaveassisted formation of TiO 2 nanocrystalline lms on a exible polymer substrate, which are suitable for use in electronics. 26 In our recent paper, 142 we also report potential applications of lowtemperature sol-gel methods for the formation of conducting coatings.

“…This was achieved by entrapment of silver nanowires within solgel materials. 142 We will dwell here only upon the samples which showed excellent combination of transparency/conductivity, and both of these samples were prepared with crystalline hydrosolsboehmite (AlOOH) and anatase (TiO 2 ). A very simple procedure was applied for preparation of the lms: mixing AgNWs and hydrosols at different ratios with subsequent spraying on a substrate.…”

Highly Thermal‐Resilient AgNW Transparent Electrode and Optical Device on Thermomechanically Superstable Cellulose Nanorod‐Reinforced Nanocomposites

“…In previous studies, it has been reported that the introduction of polyethoxysiloxane or various nanoparticles of TiO 2 , Al 2 O 3 , SiO 2 , ZrO 2 , and ZnO into the AgNW layer can improve the thermal stability of the electrodes by minimizing thermal oxidation of the AgNWs, sometimes at the expense of a reduction in transparency. [12][13][14] In our study, we successfully demonstrated a high-thermal-performing AgNW electrode with good electrooptical performance by developing a thermal dimensionally stable nanocomposite substrate that minimized the fragmentation of AgNWs. Combining our findings with those previously reported indicates that a high-performing electrode could be fabricated for application in future advanced devices.…”

“…However, ITO is not preferred for flexible electronic applications because of its brittle nature and rising cost . Therefore, nanomaterials such as carbon nanotubes (CNTs), graphene, silver nanowires (AgNWs), copper nanowires, and gold nanowires have been widely studied; these materials are able to produce a flexible conductive nanonetwork on the large‐area substrate with a relatively low density. Especially for CNTs, graphene, and AgNWs, great advancements have been made in their synthesis processes and in the fabrication method, thermal stability, and electro‐optical performance of the resulting flexible transparent electrodes .…”
