| Popis: | 98 Single-walled carbon nanotubes (SWCNTs) were purified and dispersed first, and then the SWCNTs were sprayed on the surface of Polyethersulfone (PES) as the transparent conductive layer. High optical transmittance, high thermal-resistant and anti-ultraviolet radiation PES substrate was prepared by hot-melting and thermal annealing process. The highly purified SWCNTs were obtained by treated under solution of sulfuric acid mixed with nitric acid at a ratio of 3:1 to remove the amorphous carbon and the metal impurities from the SWCNTs. SWCNTs were dispersed separately with jelly fig pectin solution under sonication before spraying the purified SWCNTs onto flexible PES substrate. The mechanism for the dispersion of the SWCNTs was proposed as well. The optical properties of the SWCNTs-coated PES substrate were investigated by ultraviolet-visible (UV-Vis) spectrometer. The adhesive ability between the SWCNTs and PES substrate was tested by bending and the surface quality of the coating layer was observed by optical microscope. The sheet resistance of the transparent conductive layer was determined by a four point probe method with a surface resistance measurement system in this study. |
