英文摘要: Abstract(#br)In this work, multiple interfaces for scattering electromagnetic waves were constructed in the poly(ε-caprolactone)/multi-wall carbon nanotube composites (PCLNT) by adding microscale glass beads (μ-GB). The high-performance microwave attenuation of the PCLNT/μ-GB composites was found to be dependent on the microwave absorption in conductive domains and the multiple scattering at interfaces. The multiple scattering was enhanced by increasing the content of μ-GBs. However, the conductive domains were separated by adding more μ-GBs, which led to reduce the absorption. Therefore, the electromagnetic interference (EMI) shielding effectiveness (SE) of the samples increased by adding low μ-GB loadings and decreased by adding high μ-GBs loadings. Fortunately, the absorption of...
