1. An electromagnetic interference shielding composite comprising a first composite layer, the first composite layer comprising:
a matrix; and
reflective particles and absorbent particles dispersed in the matrix,
wherein a size of each of the absorbent particles and the reflective particles ranges from 200 nm to 20 μm, and the size of each absorbent particle is smaller than that of each reflective particle,
wherein the reflective particles reflect an electromagnetic wave, and
wherein the absorbent particles absorb the electromagnetic wave and convert the absorbed electromagnetic wave into thermal energy which is emitted.
