Реферат:
Here a method for estimating the effective parameters (effective conductivity) of spherical aerogels of multilayer carbon nanotubes (CNTs) is proposed using the measured values of their polarizability and the wire medium model. While aerogels have a structure formed with tangles of curved nanotubes with chaotic contact distribution, the possibility to describe their electrophysical properties using the regular connected wire medium is estimated here. Calculations of the polarizability of regular structures consisting of copper and CNT wires of identical diameters (not less than 50 nm) for different models are performed. It is suggested that by selecting the parameters of a regular medium, it is possible to achieve the closeness of the polarizability values of samples of the same shape consisting of regular and irregular media. The calculated polarizability values of aerogels are consistent with the results of measurements of polarizability performed using the method of open resonators in the range 8–12 GHz. The possibility of estimating the electrophysical characteristics of carbon aerogels is considered for further modeling of the electromagnetic characteristics of composites based on them.
