▎ 摘  要

NOVELTY - Conductive composition includes a polymer resin, a metal powder, a conductive carbon material, and a solvent, where each metal powder includes a main portion and a multiple of branch parts connected to the main portion. The polymer resin is dissolved in the solvent, the metal powder and the conductive carbon material are dispersed in the solvent in which the polymer resin is dissolved. The polymer resin accounts for 10-40 wt.% of the solid content of the conductive composition, and the metal powder accounts for 40-89 wt.% of the solid content of the conductive composition. The conductive carbon material accounts for 0.1-5 wt.% of the solid content of the conductive composition, and the weight percentage of the solvent in the conductive composition is 25-40 wt.%. USE - Conductive composition is used for conductive film for circuit structure and wearable device (all claimed). ADVANTAGE - The conductive composition can be stretched and does not define a stretchable direction. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing conductive film by drying and curing the conductive composition.
