摘要

微波的热利用技术促进了吸波材料的应用研究。碳纳米管（CNTs）是近年来新兴的强吸波材料，具有密度小、比表面积大、量子尺寸效应的特点。对碳纳米管吸波材料的复介电常数和复磁导率随碳纳米管含量的变化进行探究。在此基础上，以石蜡油为蓄热介质探究了碳纳米管材料在微波辐照下吸波产热特性。同轴传输法适用于小型样品的测量，具有误差小的优点，故采用此种方法作为测量电磁参数手段。对碳纳米管电磁参数测量实验结果表明，碳纳米管吸波材料在低频下对于微波能的损耗兼具电损耗和磁损耗。对碳纳米管吸波产热特性实验结果表明，碳纳米管是一种强吸波材料。

Abstract

The microwave thermal utilization technology has promoted the application study of microwave absorbing materials. Carbon nanotubes (CNTs)， small in density

large in surface area and with quantum size effect，are new strong absorbing materials in recent years. This article investigated the complex permittivity and complex permeability of CNTs with the change of carbon nanotubes content. On basis of it

absorbing heat generation properties of carbon nanotube were explored under microwave radiation. The coaxial transmission method is suitable for the measurement of small samples which is accurate

so choosing this method to explore its electromagnetic parameters. The results show that both electrical and magnetic losses are exits in CNTs when losing microwave energy. From study of heat generation properties

it is concluded that CNTs is a material whose microwave absorbing ability is strong.
