MULTIFUNCTIONAL COMPOSITE FILM HAVING HEAT DISSIPATION AND ELECTROMAGNETIC WAVE SHIELDING/ ABSORPTION CAPABILITIES, AND PRODUCTION METHOD THEREFOR

摘要

The present invention relates to a novel type of multifunctional composite film having heat dissipation and electromagnetic wave shielding/ absorption capabilities, and a production method therefor. More specifically, the present invention has the effect of providing a composite film having heat dissipation properties and electromagnetic wave absorption properties by having a magnetic filler and a heat-dissipating filler uniformly mixed on a polymer matrix, and having electromagnetic wave shielding and heat dissipation properties by having a metal mesh dispersed on the polymer matrix, and thus exhibiting high heat dissipation in an in-plane direction and plane-transmission direction, and at the same time, having electromagnetic wave shielding and absorption capabilities.
