Directional Electromagnetic Interference Shielding Based on Step-Wise Asymmetric Conductive Networks
文献摘要：
Some precision electronics such as signal transmitters need to not only emit effective signal but also be protected from the external electromagnetic (EM) waves.Thus,directional electromagnetic interference (EMI) shielding materials (i.e.,when the EM wave is inci-dent from different sides of the sample,the EMI shielding effectiveness(SE) is rather different) are strongly required;unfortunately,no compre-hensive literature report is available on this research field.Herein,Ni-coated melamine foams (Ni@MF) were obtained by a facile electroless plating process,and multiwalled carbon nanotube (CNT) papers were prepared via a simple vacuum-assisted self-assembly approach.Then,step-wise asymmetric poly(butylene adipate-co-terephthalate) (PBAT)composites consisting of loose Ni@MF layer and compact CNT layer were successfully fabricated via a facile solution encapsulation approach.The step-wise asymmetric structures and electrical conductivity endow the Ni@MF/CNT/PBAT composites with unprecedented directional EMI shielding performances.When the EM wave is incident from Ni@MF layer or CNT layer,Ni@MF-5/CNT-75/PBAT exhibits the total EMI SE (SEr) of 38.3 and 29.5 dB,respectively,which illustrates the ASET of 8.8 dB.This work opens a new research window for directional EMI shielding composites with step-wise asym-metric structures,which has promising applications in portable electronics and next-generation communication technologies.
