ABSTRACT

To investigate the efect of gas dispersing carbon nanotubes (CNTs) and hot pressing method on the transparency and the conductivity of thin flms, the free arc was used to disperse the CNTs in a high dispersion rate, and the dispersed CNTs were rapidly pressed into the surface of the PET flm by hot pressing to obtain electrical conductivity. The relationship between the light transmission and sheet resistance of the flm was studied by changing the deposition time and the presence or absence of electrostatic adsorption. It was found that the CNTs modifed flm still retains good electrical conductivity (sheet resist�ance up to 6×104 Ω, light transmittance 69%) through the cleaning of surfactants and ultrasonic waves, which proves that hot pressing is a simple physical method to achieve efective combination of CNTs and flms.
