Effect of blend ratio on the morphology and electromagnetic properties of nanoparticles incorporated natural rubber blends

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

“…It is clear that the NR/MWCNTs/MoS 2 ‐5/5 composite shows the highest effective absorption bandwidth (RLs < −10 dB) of 3.44 GHz (14.56‐18 GHz, 1.1 mm), which is higher than that of NR/MWCNTs and NR/MoS 2 . In Figure 8B, the MA capacity of the NR/MWCNTs/MoS 2 is compared with other analogs which have been reported recently 10,12‐14,17,18,36 . It is worth noting that the MA capacity of NR/MWCNTs/MoS 2 ‐5/5 composite in this work is better than those reported in the literature, demonstrating that using MWCNTs/MoS 2 can provide the composites with competitive MA characteristics, including smaller thickness, higher absorption efficiency and broader effective absorption bandwidth.…”

“…Compared with traditional metal‐based MA materials that easily suffer from some shortcomings such as high density, poor adaptability, cumbersome processing and susceptibility to corrosion, 5‐7 elastomeric composites have been considered to be an alternative in designing an absorber along with superior absorption capability and wide effective bandwidth 8‐10 . In addition, elastomeric composites engage complex absorption mechanism, which is associated with the different hierarchy of scales, and can be controlled by tuning the morphology of nanofillers 11‐13 …”

Compatibility-tuned distribution of nanoparticles in co-continuous rubber structures toward microwave absorption enhancement

“…17,24,25 Hereto, the validity of the proposed correlations is evaluated based on our previous studies, in which it has been conrmed that CCB nanoparticles are preferentially located distributed in NR phase. 20 As the DMA results shown in Fig. 1, the compatibility of NR and ENR-25 is better than that of NR and ENR-40, evidenced by smaller gap between the tow characteristic tan d peaks.…”

“…Moreover, the MA performance of the composites can be efficiently tuned via adjusting the NR/ENR ratio. 20 Rationale behind the present work is to investigate whether compatibility of NR/ENR blends can be used as a tool to tune the distribution of CCB, potentially resulting in intact dielectric/magnetic loss network and higher MA capacity.…”

Effect of conductive polyaniline in thermoplastic natural rubber blends on the mechanical, thermal stability, and electrical conductivity properties

“…who prepared the HDPE/linear LDPE (LLDPE)/PANI conductive blend via melt compounding has reported that the electrical conductivity increased and achieved to a power scale of 10 −6 when the 40 wt % PANI was added as compared to 0, 5, 10, 15, and 20 wt % PANI (showing insignificant improvement of electrical conductivity ~10 −11 S cm −1 ). There are other factors that affect the conductivity properties, for instance, the inclusion of nanofillers or nanoparticles would lead to good dispersion of filler in the matrix and thus improving the conductivity of composite materials …”
