【 摘 要 】

tsNi@MF/CNT/PBAT composites with step-wise asymmetric structures are fabricated via a facile solution encapsulation approach.The composites exhibit the unprecedented directional electromagnetic interference shielding performances (ΔSET = 8.8 dB), which are further verified by an actual application measurement in a remote controlled toy car system.
