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

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...

Description
Summary: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 (MoS2). Evidenced by the morphological results, the restacking of MoS2 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 MoS2, the resulted NR/MWCNTs/MoS2 nanocomposites showed higher electromagnetic properties than their NR/MWCNTs and NR/MoS2 counterparts did. The reflection loss of NR/MWCNTs/MoS2 composites with 5 vol% MWCNTs and 5 vol% MoS2 is −49.04 dB, which is 9.2 and 21.9 times stronger than that of sole MWCNTs or MoS2 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.
