Synthesis of Silver Nanowires by Using Tetrabutyl Ammonium Dibromochloride as the Auxiliary for Low-Haze Flexible Transparent Conductive Films

Silver nanowires (AgNWs) with the diameter down to 16 nm have been synthesized by using tetrabutyl ammonium dibromochloride (TBADBC) as the organic auxiliary. Moderate dosage of TBADBC was proven to be favorable for the in situ growth of Ag pentahedral seeds on the surface of small AgClBr2 particles and have a passivation effect on the Ag{100} crystal facet during the growth of AgNWs, eventually resulting in the formation of thin AgNWs. Furthermore, the transparent conductive film fabricated by using the obtained AgNWs exhibited excellent photoelectric properties, which has a transmittance of 90.60%, a haze of 0.95%, and a sheet resistance of 110.8 Ω/sq, indicating large potential for application in flexible transparent conductors.
