Silane coupling agent modified nickel nanoparticles and its electromagnetic characters
Source abstract
Abstract
The oxide layers of Ni nanoparticles were removed by acid hydrochloric dilute,then modified by silane coupling agents(KH-550).The modified nanoparticles were characterized by activation index,IR etc.The electromagnetic parameters were measured with the method of coaxial wave-guide by Agilent 8722ES microwave network analyzer.The electromagnetic wave losses were simulated with the measured electromagnetic parameters.It is indicated that 5wt% silane coupling agents is the best concentration for modification of Ni nanoparticles,with which the best dispersion and improved electromagnetic wave absorption were obtained.
