Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Enhanced interfacial polarization is one of the most effective methods for efficient electromagnetic wave absorbing (EMA) performance. In this study, we propose a cladding morphology modulation strategy for preparing high-performance PPy/MWCNTs(PC) by controlling the polymerization cladding morphology of PPy through acid doping using an in-situ polymerization method. By constructing a 3D network structure with a rough surface, many interfaces and pore spaces are generated to increase the multiple reflections and scattering of electromagnetic wave energy, improve the interfacial polarization of the material, and enhance the polarization relaxation process. Meanwhile, the 3D conductive network generated by the cladding provides a channel for electron transfer between MWCNTs and PPy nanoparticles and PC nanorods, which improves the conductivity loss of the material and allows more electromagnetic wave to be dissipated in the form of thermal energy. With the doping acid of p-toluene sulfonic (TsOH), the EMA absorption performance of PC composites can reach a maximum reflection loss(RL) of -60.21 dB at the frequency of 8.24 GHz, and the best effective bandwidth (EAB) of 5.04 GHz for single thickness and 14.08 GHz for full-thickness (EAB), providing excellent EMA performance.
