Improved microwave absorbing performance of natural rubber composite with multi‐walled carbon nanotubes and molybdenum disulfide hybrids

Abstract

Multicomponent nanocomposites demonstrate many properties that are not found in their mono‐counterparts. Here, natural rubber (NR) composites with improved electromagnetic properties were prepared via incorporating hybrids of one‐dimensional multi‐walled carbon nanotubes (MWCNTs) and two‐dimensional molybdenum disulfide (MoS 2 ). Evidenced by the morphological results, the restacking of MoS 2 and the tortuous of MWCNTs are effectively inhibited due to the depletion‐effect of the different dimensional nanoblocks. Owing to the synergetic effect of MWCNTs and MoS 2 , the resulted NR/MWCNTs/MoS 2 nanocomposites showed higher electromagnetic properties than their NR/MWCNTs and NR/MoS 2 counterparts did. The reflection loss of NR/MWCNTs/MoS 2 composites with 5 vol% MWCNTs and 5 vol% MoS 2 is −49.04 dB, which is 9.2 and 21.9 times stronger than that of sole MWCNTs or MoS 2 filled NR composites, respectively. Such composite with excellent microwave capacity could be used as a new kind of candidate for the new types of microwave absorbing materials.
