摘要:
There is provided a conductive film and a method for preparing same. The conductive film is prepared by forming a prime-coating layer of a three-dimensional network structure on a base and by applying a semiconductive compound-containing solution onto the prime-coating layer to form a conductive layer. The conductive film is excellent in conductivity and transparency as well as adhesion of the conductive layer.
