Abstract-F Electromagnetic and thermal properties of three-dimensional printed multilayered nano-carbon/poly(lactic) acid structures
A new type of light-weight produced by consisting of nano-carbon polymer layer followed by a dielectric polymer layer is proposed. We performed temperature dependent characterization and measured the electromagnetic (EM) response of the samples in the GHz and THz range. The temperature dependent crystallization, and melting were observed to be strongly affected by the presence and the number of nano-carbon layers in the sandwich The electromagnetic measurements show a great potential of such a type of periodic for electromagnetic compatibility applications in frequency range. Sandwich containing only two nano-carbon layers already become not transparent to the giving an electromagnetic interference shielding efficiency at the level of 8–15 dB. A sandwich consisting of one nano-carbon and one polymer layer is opaque for THz radiation, because of 80% of absorption. These studies serve as a basis for design and realization of specific optimal geometries of meta-surface type with the technique, in order to reach a high level of electromagnetic interference shielding performance for real world EM cloaking and EM ecology applications.
