Formation of layered nanofibric materials and composite coatings

Abstract

Using an electrospinning device, we determined the optimal conditions for producing nanofibers from a 10% solution of Co–AN. These conditions involved applying a 15[Formula: see text]kV voltage to the anode, which was connected to the syringe containing the solution, and maintaining a distance of 12–15[Formula: see text]cm from the needle tip to the collector screen (cathode). The filament diameter (d) ranged from 0.2 to 0.5[Formula: see text]mm. This setup allowed the formation of nanofibers under the cover. The electrolysis process was conducted for varying durations, ranging from 4 to 14[Formula: see text]h, while applying currents of 2[Formula: see text]mA, 4[Formula: see text]mA, and 8[Formula: see text]mA. At 4[Formula: see text]mA and 8[Formula: see text]mA, a substantial portion (approximately 65–70%) of the macroions in the solution reassembled on the electrode surfaces. These images clearly illustrate the restoration of macroions on the electrode surfaces, achieved through electron exchange processes. This phenomenon results in the combination of macroions and their neutralization, leading to the formation of a composite coating on the titanium, iron plate, and rods.
