碳纳米管材料低频电磁参数及吸波产热特性
Low frequency electromagnetic parameters and absorbing heat generation properties of carbon nanotubes
摘要
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.关键词
