Manufacturing method for electro-magnetic interfernce shielding film and electro-magnetic interference shielding film using the same |
| abstract |
The present invention provides a method for preparing a polymer solution, comprising the steps of: a) dissolving a cellulose-based polymer in water to prepare a polymer solution; b) adding carbon nanotubes, copper-nickel core-shell nanoparticles having an average particle diameter of 60 to 70 nm, copper-silver core-shell nanoparticles having an average particle diameter of 30 to 40 nm and a surfactant to the polymer solution, To produce a first composition for an electromagnetic wave shielding film; c) mixing the composition with carbon black, and stirring the mixture with a paste mixer to prepare a second composition; And d) applying and drying the second composition on a substrate, wherein in step b), the copper-nickel core-shell nanoparticles and the copper-silver core-shell nanoparticles have a weight ratio of 1: 2 to 2.5 To the electromagnetic wave shielding film. |
