摘要: Polymer composites containing nanocarbon fillers are under intensive investigation worldwide due to their remarkable electromagnetic properties distinguished not only by components as such, but the distribution and interaction of inside polymer matrix. The theory herein reveals that a particular effect connected with homogeneity composite manifests itself in terahertz range. Transmission time-domain spectroscopy was applied nanocomposites obtained co-extrusion PLA additions graphene nanoplatelets multi-walled carbon nanotubes. THz peak permittivity’s imaginary part predicted model experimentally shown for GNP-containing both below above percolation threshold. physical nature explained impact on filler particles excluded from network peculiarities distribution. Terahertz versatile instrument diagnostics is discussed.
