Abstract
High-performance transparent conductive films are important components of optoelectronic devices such as photovoltaic cells and flat panel displays. This study introduces a novel method for fabricating single-walled carbon nanotube transparent conductive films via water-phase exfoliation. The interdependence among transmittance, sheet resistance, and SWCNT concentration in the films is explored. Additionally, the impact of hybrid treatments on film transmittance and conductivity is examined. The results demonstrated accurate predictions of the films’ transmittance (ranging from 50% to 96%) within the solar spectrum (300—2500 nm). Precise control over sheet resistance characteristics, ranging from 3 Ω ·sq-1 to 100 Ω ·sq-1, was achieved by adjusting the concentration of single-walled carbon nanotubes. Through the purification process of acid reflux and strong oxidation, the light transmittance increased by an average of 3.1% in the 750—2000 nm band, and the sheet resistance was reduced by more than 50%. These transparent conductive films demonstrate excellent overall performance, characterized by high transmittance and low resistance, thereby presenting extensive prospects for the advancement of optoelectronic devices.
