Abstract

Abstract This work showcases the production of flexible polydimethylsiloxane/multiwalled carbon nanotube (PDMS/MWCNT) composites with multilayer structures via the glucose template method followed by vacuum‐assisted filtration and hot pressing. The properties of the single‐layer and multilayer composites have been systematically investigated. In the X‐band, thanks to the ohmic loss, the interfacial polarization loss at the interfaces and the multiple reflections between PDMS/MWCNT layers, the 5‐layer PDMS/MWCNT composites achieves 65.9 dB. Furthermore, all multilayer PDMS/MWCNT composites present a high retention rate of about of 90% after repeated bending with curvature radius of 1.8 mm at a frequency of 1 cycle per 2 s for 1000 times. Highlights The PDMS/MWCNT composites are fabricated by the glucose template method. The 5‐layer PDMS/MWCNT composites can reach 65.9 dB in X‐band. The PDMS/MWCNT composites present high stability even after repeated bending.
