摘要

本文研究了多壁碳纳米管分散在环氧树脂中制备的纳米复合材料的电学特性。讨论了MWCNTs的形态表征、样品制备和在树脂中的分散。测量了纳米复合材料在100 kHz-12MHz和1-18 GHz范围内的复介电常数,并根据填料百分比和MWCNTs的特性讨论了复介电常数的取值。计算了不同重量百分比的MWCNTs的屏蔽效能。

Wide band characterization of MWCNTs Composites based on epoxy resin: Complex permittivity and shielding effectiveness
In this work, the electrical characteristics of nanocomposites obtained by dispersing multi walled carbon nanotubes in epoxy resins are investigated. The morphological characterization, samples preparation and dispersion of MWCNTs inside the resin are discussed. The complex permittivity of nanocomposites (in the range 100 kHz-12MHz and 1-18 GHz) is measured and its value discussed in the light of filler percentage and MWCNTs characteristics. The shielding effectiveness (SE) is computed for different weight percentage of MWCNTs.
