Title: HIGH-LOADING-LEVEL COMPOSITES FOR ELECTROMAGNETIC INTERFERENCE (EMI) APPLICATIONS
Abstract:
Electromagnetic interference (EMI) shielding composites with high-loading-level ceramic beads and methods of making and using the same are described. The composites include high-loading-level of ceramic beads distributed inside a polymer matrix. The ceramic beads have a substantially spherical shape. The ceramic beads are formed by melting ceramic powders or particles. In some cases, the ceramic beads include ferrite beads.
