▎ 摘　　要

NOVELTY - The composite film has a composition with following weight proportion as 1-5 pts. wt. of graphene, nano cellulose, 1 pts. wt. of polylactic acid, 93-97 pts. wt. of polypyrrole. The nano-cellulose is dispersed for preparing N, N-dimethyl acetamide solution. The prescription amount of graphene powder and proper amount of sodium dodecyl benzene sulfonate are added. The prescription amount of polylactic acid is added to the water bath at 50-80 degrees centigrade. The polylactic acid is dissolved and de-foamed in vacuum. USE - Polymer/graphene flexible conductive composite film. ADVANTAGE - The heat stability of the composite conducting ability is improved. The surface of the conductive film is smooth. The conductivity is improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method for polymer/graphene flexible conductive composite film. DESCRIPTION OF DRAWING(S) - The drawing shows a scanning electron microscope photograph of polymer/graphene flexible conductive composite film.
