The present invention relates to a doped organic semiconductor thin film and a method for producing the same. The method for producing a doped organic semiconductor thin film of the present invention includes dissolving a dopant material in an organic solvent having strong polarity so that doping does not occur in the solution even when mixed with an organic semiconductor material, thereby eliminating the precipitation phenomenon of a composite dopant material in a doping process performed in a solution phase. In addition, an organic semiconductor thin film produced by the method has an effect of improving electrical conductivity by inducing a high level of doping.

To address the issue of poor adhesion of existing water-based conductive coatings on the surface of oil-contaminated aluminum foil, the present application provides a carbon material and a preparation method thereof, a water-based conductive coating, and a carbon-coated aluminum foil. The method includes the following steps: mixing water, an alcoholizing agent, and the carbon material uniformly and performing an alcoholization treatment; and modifying the alcoholized carbon material using a surface modifier. The surface modifier includes one or more of hydroxyalkanoates or phosphates to obtain a modified carbon material. In the present application, the alcoholization treatment increases the number of hydroxyl groups on the surface of the carbon material available for grafting. Subsequently, the carbon material is modified with the surface modifier. The modified carbon material possesses an affinity for rolling oil. When applied in a water-based conductive coating, it can work in synergy with the high oil absorption characteristics of the carbon material to break through the "blockade" of the oil film. This allows the polar groups in the coating resin to contact the substrate and generate attractive forces, leading to improved adhesion. In the water-based conductive coating, the filling amount of the carbon material can be further increased to reduce coating resistance.
