Abstract
Abstract 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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
88 words
A conductive film prepared by forming a prime-coating layer of a three-dimensional polymeric network structure on a base and by applying a semiconductive compound-containing solution onto the prime-coating layer to form a conductive layer, wherein the prime-coating layer is one of which degree of swelling T 1 /T 0 is within the range of 1.05 to 2.5, wherein T 0 is the thickness of resin before immersion and T 1 is the thickness of resin after immersion into the solvent of the semiconductive compound solution for five minutes.
Claim 2
Dependent Claim
88 words
A conductive film prepared by forming a prime-coating layer of a three-dimensional polymeric network structure on a base and by applying a semiconductive compound-containing solution onto the prime-coating layer to form a conductive layer, wherein the prime-coating layer is one of which degree of swelling T 1 /T 0 is within the range of 1.05 to 2.5, wherein T 0 is the thickness of resin before immersion and T 1 is the thickness of resin after immersion into the solvent of the semiconductive compound solution for five minutes.
