Paper Abstract

An ultra-flexible and low-sheet resistance transparent conductive film is developed from nickel metal-mesh (Ni metal-mesh) embedded in a polyimide (PI) by exploiting selective deposition technique coupled with photolithography and subsequent inverted film-processing method. The fabricated conductive film achieved sheet resistance values as low as 0.15 Ω sq-1, with corresponding optical transmittance as 80% at 550 nm corresponding the figure of merit up to 1.1×104. The film shows excellent adhesion and also preserves its structural integrity and good contact with the substrate for severe bending showing less than 4% decrease of conductivity even after 104 cycles. Finally, employing the fabricated Ni metal-mesh/PI conductive film, a hybrid transparent thin-film heater is demonstrated, which exhibited higher heating temperatures (110°C) under the lower operating voltage (1 V), lower power consumption (79.1°C cm2 W-1), and shorter response time (T < 2 s) than other heaters, as well as stability after repeated test.
