Abstract
A substrate includes a base substrate and a conductive pattern provided disposed on the base. A material of the conductive pattern includes a second conductive polymer and a dopant. The second conductive polymer is a conductive polymer transformed from a first conductive polymer under an action of the dopant. A conductivity of the second conductive polymer is greater than a conductivity of the first conductive polymer
Claims21
A substrate, comprising a base substrate and a conductive pattern disposed on the base substrate, wherein
- a material of the conductive pattern includes a second conductive polymer and a dopant, and the second conductive polymer is a conductive polymer transformed from a first conductive polymer under an action of the dopant;
- and
- a conductivity of the second conductive polymer is greater than a conductivity of the first conductive polymer.
(canceled)
A method of fabricating a conductive film, comprising:
- making a surface of a base substrate on which films are to be formed positively or negatively charged;
- immersing the base substrate in a mixed solution for a period of time, taking out the base substrate from the mixed solution and drying the base substrate, so as to form a layer of sub-conductive film on the surface of the base substrate on which films are to be formed, the mixed solution including a second conductive polymer and a dopant, and the second conductive polymer being a conductive polymer transformed from a first conductive polymer under an action of the dopant;
- repeating a process of immersing the base substrate formed with a layer of sub-conductive film in the mixed solution for a period of time, taking out the base substrate from the mixed solution and drying the base substrate at least once;
- and
- forming a plurality of layers of sub-conductive films on the base substrate through the above steps, the plurality of layers of sub-conductive films constituting the conductive film.
