Abstract
Silver nanowire (AgNW) has become one of the best candidates for flexible transparent electromagnetic (EMI) shielding materials, while the low corrosion resistance of AgNW hinders its application in environments with high content of corrosive substances. Herein, an AgNW/poly(3,4-ethylene dioxythiophene)/poly(styrene sulfonate) (PEDOT:PSS)@nickel electrode was prepared through ultrasonic spray coating and electroplating methods. PEDOT:PSS is sprayed to improve the conductivity of the AgNW network, and a 9.8–16.5 nm Ni layer is deposited on the AgNW/PEDOT:PSS to protect the AgNWs from corrosion. The AgNW/PEDOT:PSS@Ni electrode shows a sheet resistance of 29 Ω·sq−1, a transmittance of 78.18 %, an average EMI shielding efficiency of 19.64 dB and excellent corrosion resistance in Na2S solution. The resultant AgNW/PEDOT:PSS@Ni electrode is promisingly used in high corrosion resistance transparent EMI shielding film.
